Flashcards in Plant And Animal Cells Deck (17):
1

What makes up an animal cell?

Cell membrane
Nucleus
Cytoplasm
Mitochondria
Ribosomes

2

What makes up a plant cell?

Cell membrane
Nucleus
Cytoplasm
Mitochondria
Ribosomes
Cell wall
Central vacuole
Chloroplasts

3

In the cell cytoplasm we have ...

Organelles

4

What is an organelle?

Number of organised or specialised structures within a living cell

5

Cells that have a nucleus are called...

Eukaryotic cells

6

Describe the function of a cell membrane

Like a very thin bag
Holds cytoplasm and organelles
Controls what enters and leaves the cell e.g. Oxygen, carbon dioxide, glucose

7

Describe function of nucleus

Large structure that contains genes that control the activities of the cell . Genes in the chromosomes
Chromosomes are coiled DNA

8

Describe cytoplasms function

Jelly like substance that fills the cell
Lots of chemical reactions take place here

9

Describe the functions of mitochondria

Tiny structures where respiration takes place, releasing energy for cell processes
Just be seen with a light microscope
(Looks a bit like a jellybean)

10

Describe the function of ribosomes

Where proteins are made(protein synthesis)

Present in cytoplasm but not visible really, can't be seen with a light microscope

11

Describe the functions of the cell wall

Made of cellulose
Supports and protects the cell

12

Describe the functions of a vacuole

Stores cell sap
Helps to keep the cell firm and rigid

13

Describe function of chloroplasts

Contains chlorophyll, which traps energy transferred from the sun

Energy is used for photosynthesis

14

What does turgid mean

Rigid

15

Muscle cells contain more mitochondria than skin cells. Why?

Muscle cells respire more
Need more energy
They carry out aerobic respiration and produce energy

16

Plants don't have skeletons. Suggest how they stand upright

Plant is supported by cell wall around each cell and the vacuole in each cell when it is full

17

Explain why not all plant cells have chloroplasts

Not all plant cells photosynthesise
E.g. Root hair cells
Cells that do not photosynthesise do not need chloroplasts
