Flashcards in Chapter 1 Deck (36):
1

Cell Membrane

Cell Membrane: The cell membrane is a barrier that separates from the cytoplasm and the outside environment.

2

Nucleus

Nucleus: The nucleus is the control station of a cell and is in the center of a cell.

3

Nuclear Membrane

Nuclear Membrane: The nuclear membrane goes around the nucleus and controls what comes in and out.

4

Chromatin

Chromatin: Chromatin is the material in the cell that contains DNA and carries genetic material.

5

Nucleolus

Nucleolus: Nucleolus is where ribosomes are made.

6

Cytoplasm

Cytoplasm: Cytoplasm is the gel like area between the membrane which many organelles are found.

7

Mitochondria

Mitochondria: Mitochondria is rod shaped cell structures that produce most of the cells energy to carry out its duties.

8

Endoplasmic Reticulum

Endoplasmic Reticulum: Endoplasmic Reticulum is cell structure that sends Proteins and other material from one part of a cell to another.

9

Ribosomes

Ribosomes: Ribosomes is a tiny structure in the cytoplasm of a cell where proteins are made.

10

Golgi Bodies

Golgi Bodies: Golgi bodies receive material from the endoplasmic reticulum and send them to other parts of the cell. They also release material outside the cell.

11

Vacuoles

Vacuoles: Vacuoles store water, food, and waste

12

Lysosomes

Lysosomes: Lysosomes contains chemicals to break down food particles and worn-out parts.

13

Cell Wall

In plants only, give the cell its shape

14

Chlororplasts

capture sunlight to make food for plants

15

Autotrophs

use food they make as energy

16

Heterotrophs

cannot make own food; get it from sun in a indirect way such as eating another living thing

17

Homeostatis

maintain stable conditions in its surroundings

18

Magnification

ability to make larger

organism

living things

20

cell

basic unit of structure and function

21

Unicellular

single-celled organisms

22

Multi-cellular

many cell organisms

23

Developement

process of change

24

Reproduce

to produce offspring

25

Spontaneous Generation

mistaken idea that living things arise from nonliving things

26

Stimulus

A change in an organism’s surroundings that causes the organism to react.

27

Response

An action or change in behavior that occurs as a result of a stimulus.

28

Microscope

An instrument the make small objects look larger.

29

Compound Microscope

A light microscope with more than one lens.

30

Cell Theory

The relationship between cells and living things.

31

Convex Lens

A curved lens in which the center is thicker than the edges.

32

Resolution

The ability to clearly distinguish.

33

A tiny cell structure that carries out a specific function in the cell.

A tiny cell structure that carries out a specific function in the cell.

34

Prokaryote

An organism which the cells lack a nucleus.

35

Eukaryote

An organism with cells that contain a nuclei.

36

Fossil

A preserved remains or traces of an organism from the past.
