1.1 cell structure ( bacteria, animal & animal )

What is a cell?

The basic structural and functional unit of all living organisms.

What is the function of the nucleus?

Contains genetic material and controls the activities of the cell.

What is the function of the cytoplasm?

The site of chemical reactions in the cell and fills the cell

What is the function of the cell membrane?

Controls the movement of substances into and out of the cell.

What is the function of mitochondria?

The site of aerobic respiration, releasing energy for cell processes

What is the function of ribosomes?

The site of protein synthesis.

What is the function of the cell wall?

Provides support and structure to a cell

What is the function of chloroplasts?

The site of photosynthesis to make food for the plant.

What is the function of the vacuole?

Contains cell sap and helps maintain turgor pressure.

Draw and label an animal cell

Nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.

Draw and label a plant cell

Nucleus, cytoplasm, cell membrane, cell wall, chloroplasts, vacuole and mitochondria.

State two differences between plant and animal cells

Plant cells have a cell wall and chloroplasts, animal cells do not.

whats the difference between eukaryotic and prokaryotic cells

• eukaryotic cells are larger than prokaryotic

• eukaryotic cells contain membrane bound organisms, prokaryotics do not

• eukaryotics keep there dna in the nucleus while prokaryotics keep them loose in the cell

for plant, animal and bacteria cells state whether they are eukaryotic or prokaryotic

plant cell - eukaryotic

animal cell - eukaryotic

bacteria cells - prokaryotic

5 organelles found in both plant and animal cells

1. cell membrane

2. ribosomes

3. nucleus

4. cytoplasm

5. mitrochondria

where can we find chlorophyll and what does it do

• it absorbs light energy for photosynthesis and contains green pigment

• found in chloroplast

bacteria cell wall is made of

peptidoglycan

where iand what is the bacteria cells chromosomal dna

a single loop of chromosomal dna that lies free in the cytoplasm

what is the role of a flagellum

to enable movement of cell

draw and label a bacteria cell

,Checklist for drawing: Cell wall, Cell membrane, Cytoplasm, Circular DNA, Plasmid (optional), Ribosomes, Flagella (if present)

whats the difference in flagella and flagellum

• flagella is plural

• flagellum is singular

plasmids are

additional genes not found in chromosomes
