Question 8

Cytoplasm

Answer 8

the material or protoplasm within a living cell, excluding the nucleus.

Question 9

Mitochondria

Answer 9

an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).

Question 10

Golgi Apparatus

Answer 10

a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport.

Question 11

Endoplasmic Reticulum

Answer 11

a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually

Question 12

Ribosomes

Answer 12

a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Question 13

Centrioles

Answer 13

a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers

Question 14

Chloroplast

Answer 14

in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.

Question 15

Vesicle

Answer 15

a small fluid-filled bladder, sac, cyst, or vacuole within the body.

Question 16

Vacuole

Answer 16

a small cavity or space in tissue, especially in nervous tissue as the result of disease.

Question 17

Nucleus

Answer 17

a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.

Question 18

Nuclear membrane

Answer 18

A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. The nuclear membrane consists of two lipid bilayers—the inner nuclear membrane, and the outer nuclear membrane.

Question 19

DNA

Answer 19

the fundamental and distinctive characteristics or qualities of someone or something, especially when regarded as unchangeable.

Question 20

Mitochondria

Answer 20

an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).

Question 21

Lysosome

Answer 21

an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.

Question 22

Multi-cellular organism

Answer 22

Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.

Question 23

Unicellular organism

Answer 23

A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.

Question 24

Prokaryote

Answer 24

a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.

Question 25

Eukaryote

Answer 25

an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.

Question 26

Cell

Answer 26

the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.

Question 27

Tissue

Answer 27

any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

Question 28

Organ

Answer 28

a large musical instrument having rows of tuned pipes sounded by compressed air, and played using one or more keyboards to produce a wide range of musical effects. The pipes are generally arranged in ranks of a particular type, each controlled by a stop, and often into larger sets linked to separate keyboards.

Question 29

Organ system

Answer 29

In biology, an organ system is a group of organs that work together to perform one or more functions. Each does a particular job in the body, and is made up of certain tissues.

Question 30

Organism

Answer 30

the material structure of an individual life form.

Question 31

Circulatory system

Answer 31

the system that circulates blood and lymph through the body, consisting of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands.

Question 32

Excretory system

Answer 32

The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body.

Question 33

Digestive system

Answer 33

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).

Question 34

Respiratory system

Answer 34

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe.

Question 35

Muscular system

Answer 35

The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body.

Question 36

Nervous system

Answer 36

the network of nerve cells and fibers that transmits nerve impulses between parts of the body.

Question 37

Sensory system

Answer 37

A sensory system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception.

Question 38

Skeletal system

Answer 38

skeletal system definition. The framework of the body, consisting of bones and other connective tissues, which protects and supports the body tissues and internal organs. The human skeleton contains 206 bones, six of which are the tiny bones of the middle ear (three in each ear) that function in hearing.

Question 39

Fight or flight reaction

Answer 39

The fight-or-flight response (also called the fight, flight, freeze, or fawn response in post-traumatic stress disorder, hyperarousal, or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.
