Biology - Plant, Specialised Cells and Animal cells

Question 1

What does multi-cellular mean?

Answer 1

An organism (living thing) that consists of many cells

Question 2

Are plant and animal cells multicellular?

Answer 2

Ye both are

Question 3

What do animal and plant cells have in common?

Answer 3

Cytoplasm 
Cell membrane 
Nucleus
Mitochondria 
Ribosomes

Question 4

What do plant cells have that animal cells don’t?

Answer 4

Vacuole
Cell wall
Chloroplasts

Question 5

What is the nucleus of a cell?

Answer 5

It’s like the brain of the cell, it is a small circular structure which contains the cells genetic information (DNA, GENES, CHROMOSONES)

Question 6

What is the cytoplasm?

Answer 6

It’s the liquid inside cells, where reactions including respiration occurs

Question 7

What is the cell membrane?

Answer 7

It’s a flexible thin material on the outside of cells that controls what comes in and out.

Question 8

In plants where is the cell membrane?

Answer 8

Just inside the cell wall

Question 9

What is the cell wall?

Answer 9

Rigid external structure that provides support and shape for the plant cell, it is made cellulose

Question 10

What is the vacuole?

Answer 10

It is the large section in the middle of many plant cells where sugars and salts are stored

Question 11

What are chloroplasts?

Answer 11

They are small green structures, they contain chlorophyll for photosynthesis

Question 12

Are mitochondria found in both plant and animal cells?

Answer 12

Both, they are Small oval structures they are found in the cytoplasm and respiration occurs in them

Question 13

What is an organelle?

Answer 13

It’s a tiny cellular structure which performs specific functions within a cell, for example nucleus

Question 14

List 4 organelles within a cell?

Answer 14

Mitochondria- respiration
Ribosome- makes protein
Nucleus- houses genetic info
Cytoplasts (only in plants)- photosynthesis

Question 15

Tell me more about what a ribosome does?

Answer 15

It is a complex molecule of RNA and proteins, they make a factory for making proteins from amino acids

Question 16

Tell more about what a mitochondria does?

Answer 16

They are found in large numbers in cells, they are where the biochemical processes of respiration and energy production occur

Question 17

Specialised cells

Red blood, what is it?

Answer 17

They are found in the blood so in animals only, they are circular, have a dipped shape to increase the surface area to be able to absorb a lot of oxygen, they don’t have a nucleus

Question 18

Specialised cell

Sperm cell and Egg cell, what are they?

Answer 18

They are the sex cells that will in the future possibly form a new young organism when fertilisation occurs

Question 19

Describe a sperm cell?

Answer 19

It is the make reproductive cell, it has 2 parts,tail and head, this design helps it to carry out its function,the head contains a nucleus to pass on genetic information when fertilisation occurs. The tail is stream lined and needs a lot of energy to swim and find an egg

Question 20

What is another name for a sperms tail?

Answer 20

Axial filament

Question 21

What is another name for the head of the sperm cell?

Answer 21

Acrosome, it contains the nucleus

Question 22

Specialised cells

Root hair cell, what is it?

Answer 22

Found in the roots of plants (at the edge), it has a long root hair to increase the surface area to absorb as much water as possible

Question 23

Specialised cells
Palisade cells (plants only) what are they?

Answer 23

They are green cells packed full of chloroplasts which contains chlorophyll they enable photosynthesis to occur

Question 24

What is photosynthesis?

Answer 24

Plants capture light energy and convert carbon dioxide and water into energy stores

Question 25

Specialised cells

Egg cell, what are they?

Answer 25

Large cell that contains an energy store to enable a young organism to develop when the egg is fertilised

Question 26

How would you recognise a lung cell?

Answer 26

A lung cell would have a big surface area on one side to allow gas exchange
