Plant cells and animal cells

Science yr 8 T2 Checkpoint revision

what cell has a cell wall

plant cell

what cell has chroloplast

plant cell

how many vacuoles does plant and animal cells have

plant cells have 1 vacuole while animal cells have many

what cell has lysosome

animal cell

what cell has centrosome

animal cell

why does plant cell have square shap

because it has a cell wall

why do animal cells have an irregular shape

because it has no cell wall

what do all cells have

cell membrane, cytoplasm, DNA

what is cell membrane

is the ‘skin’ of the cell and controls what goes in and out of the cell (nutrient in adn waste out)

what is cytoplasm

it provides structure to the cell and contains dissolved nutrient and waste products. It is jelly like

what is Dna

It is the instructions for every job the cell need to do. It passed down from generations.

Is the set of Dna same in each cellof an organism

yes

how do plants and animal cells cover the DNA

with membrane and it forms a nucleus

What is mitochondria

site of energy production in the cell and the powerhouse of the cell.

Does the amount of mitochondria differ in each cell (give example)

yes, it varies based on what job it does. For example muslce cells have more mitochondria than skin cells due to their high energy requirements.

What are vesicle

The store water, nutrients and waste products

what is the cell wall (what would happen without it_

it helps keep the cell in shape, without it in freshwater, the cell membrane may burst

What is chroloplasts

They use the sunlights energy to rearragne carbon dioxide and water molecules into glucose and oxygen. (photosythesis turn solar energy in chemical energy). Plants are green because of it.
