Cells

Question 0

Plant cells have all the things that human cells have, but what extra parts do they have?

Answer 0

Rigid cell wall, permanent vacuole and chloroplasts

Question 1

What do human and animal cells contain?

Answer 1

Nucleus, cytoplasm, cell membrane, mitochondria and ribosomes

Question 2

What does a nucleus do?

Answer 2

Contains genetic material to control what happens in the cell

Question 3

What does a cytoplasm do?

Answer 3

This where most of the chemical reactions happen, it contains enzyme a which control the chemical reactions

Question 4

What does a cell membrane do?

Answer 4

Holds the cell together and controls what goes in and out of the cell

Question 5

What does a mitochondria do?

Answer 5

Most of the reactions for respiration take place here which release energy for the cell to work

Question 6

What does a ribosome do?

Answer 6

Makes proteins

Question 7

What does a cell wall do?

Answer 7

It supports the cell and strengths it

Question 8

What does a permanent vacuole do?

Answer 8

Contains cell sap which is a weak solution of sugar and salt

Question 9

What does a chloroplast do?

Answer 9

Photosynthesis occurs here

Question 10

What is yeast?

Answer 10

A microorganism which is a single called organism

Question 11

What does a yeast cell have?

Answer 11

Nucleus, cytoplasm, cell membrane and a cell wall

Question 12

What is bacteria?

Answer 12

A microorganism which is a single celled organism

Question 13

What does a bacteria cell have?

Answer 13

Cytoplasm, cell membrane and a cell wall

Question 14

What are the 5 specialised cells?

Answer 14

Palisade leaf cells, guard cells, red blood cells, sperm cells and egg cells

Question 15

What do specialised cells do?

Answer 15

Carry out a particular function

Question 16

What are palisade leaf cells adapted for and how?

Answer 16

Photosynthesis - packed with chloroplasts at the top of the cell, talk shake means a large surface area and a thin shake means there are a lot of them at the top of the leaf

Question 17

What are guard cells adapted for and how?

Answer 17

Open and close pores - kidney shape which opens and closes the stomata, when the plant has lots of water they fill up and go turgid which makes the stomata open and gases are exchanged and they’re sensitive to lights and close at night

Question 18

What are red blood cells adapted for and how?

Answer 18

Carry oxygen - concave shape for a big surface area to absorb oxygen, packed with haemoglobin and they have no nucleus so there’s more room for haemoglobin

Question 19

What are sperm cells adapted for and how?

Answer 19

To get the make DNA to the female DNA - long tail, streamlined head to help it swim with a lot of mitochondria so it has enough energy to swim and they carry enzymes to digest the egg cell membrane

Question 20

What are egg cells adapted for and how?

Answer 20

To carry female DNA and to nourish the embryo - it had huge food reserves to feed the embryo and the membrane changes when it fuses with sperm to stop anymore getting in

Question 21

What do specialised cells form, in order from smallest to biggest?

Answer 21

Cell, tissue, organ and an organ system

Question 22

What is a tissue?

Answer 22

A group of similar cells that work together to carry out a particular function

Question 23

What is the function of an epithelial tissue?

Answer 23

It covers some parts of the body for example, the inside of the gut

Question 24

What is an organ?

Answer 24

A group of different tissues that work together to do a certain function

Question 25

The stomach is an organ, what tissues is the stomach made up of?

Answer 25

Muscular, glandular and epithelial tissues

Question 26

What is an organ system?

Answer 26

A group of organs working together to do a certain function

Question 27

What organs are in the digestive system?

Answer 27

Glands, stomach, liver, small intestine and the large intestine
