Cells and Systems Flashcards
(54 cards)
Organ
Group of Tissues that work together to perform a specific Function. Ex: Heart
Organ System
A group of organs that do a certain task, such as digestion and breathing. Ex: Respiratory System
Compound Light Microscope
Microscope that has two or more lenses that has a light source.
Mycoplasma
Type of microscopic Organisms. EX:Bacteria
Multicellular
Made of more than 1 Cell
Ex:Animals
Unicellular
Made of just one cell. Ex:Acetabularia, amoeba
Diffusion
The movement of substance from an area of higher concentration to an area of lower concentration.
Osmosis
Diffusion of water through a selectively permeable membrane
Specialized Cells
Cells that have specific structures that help them perform particular function. Ex: Red Blood cell
Tissues
Group of similar cells working together to perform a specific function. Ex: Muscles tissue

What are the three types of tissues of plants?
Photosynthetic
Protective
Transport
4 Types of Tissues found in animals/Humans?
Nervous
Connective
Epithelial
Muscle
3 Organs of plants
Roots

What are the Six factors of an organism?
- They must be made up of cells
- Need Energy
- Grow and Develop
- Respond to the environment
- Reproduce
- Adaptations
What are the three types of adaptations?
Behavioural-Responses (chooses)
Structural- Physical Features
Phycological -
Responses (Not chooses) Ex:Heart rate
Cell Membrane
A thin covering that surrounds the cell. Protects the cell Gives the cell its shape Allows materials to enter and leave cell Help keeps cell material together
Cytoplasm
The living material inside the cell membrane but outside of the nucleus. Helps give cell shape
Most life function take place within cytoplasm
Nucleus
Often found near the center of the cell. The Boss of the cell, very important during reproduction.
Nuclear membrane
A thin covering that surrounds the nucleus, controls the passage of what goes in and out of the nucleus, and helps keep its shape.
Mitochondria
Rod shaped. “Power houses” of the cell. Release and stored the energy the cell needs.
Endoplasmic Reticulum
a network of channels. Like a series of roadways. They are used for loving materials within the cell.
Ribosomes
Tiny grainlike structures. make and store protein m, mostly found on the endoplasmic reticulum , some however moves freely within the cytoplasm
