Specialised Cells

Question 1

What are different about specialised cells?

Answer 1

They have a particular function

Question 2

What is the specialised cells for digestion?

Answer 2

Small intestine epithelial cells

Question 3

What do small intestine Epithilial cells do?

Answer 3

( lining cells )

Allow for absorption of digested food molecules.

Question 4

What is special about the small intestine epithilial cells?

Answer 4

Small folds called microvilli which increase surface area for efficient food absorption

Question 5

What does a small intestine epithelial cell consist of?

Answer 5

Nucleus
Mitochondria
Cytoplasm

Question 6

Why does the small intestine contain lots of mitochondria?

Answer 6

To release energy for smooth muscle contraction

This pushes food through the digestive systems

Question 7

Why does the pancreas produce lots of enzymes?

Answer 7

For digestion of large insoluble food molecules to be broken down to smaller soluble food molecules

Question 8

Enzymes are

Answer 8

Proteins

Question 9

Proteins are made in the

Answer 9

Ribosomes

Question 10

Pancreas contains lots of

Answer 10

Ribosomes

Question 11

What are sex cells called

Answer 11

Question 12

Animal male gametes are called

Answer 12

Sperm

Question 13

Female animal gametes are called

Answer 13

Question 14

Plant sex cells male are called

Answer 14

Question 15

Female plant sex cells are called

Answer 15

Ovum or egg

Question 16

What does a human egg cell consist of

Answer 16

Cytoplasm 
Nucleus 
Ribosomes 
Mitochondria

Question 17

How many chromosomes are there in a nucleus in a human egg cell

Answer 17

46 chromosomes
23 pairs
Haploid = n

Question 18

What does a sorry cell consist of

Answer 18

Tail (flagellum)
Mitochondria

Haploid nucleus

Question 19

When the egg and speed fuse and become a diploid nucleus the cell divides to produce a ball of identical cells called a

Answer 19

Zygote

Question 20

After about 14 days a zygote is called a

Answer 20

Embryo

Question 21

After a few weeks of egg n spend fusion it’s called a

Answer 21

Fetus

Question 22

It’s called a baby only when

Answer 22

It’s been born

Question 23

What’s the tail specialised for

Answer 23

Helps sperm to swim to the egg cell for fertilisation

Goes side to side

Question 24

How is mitochondria an adaptation

Answer 24

Releases lots of energy helping sperm to swim

Where respiration occurs

Question 25

How is acrosome and adaptation

Answer 25

Contains enzymes to digest a way through the egg cell membrane

Question 26

How is the protective jelly layer an adaptation

Answer 26

Protects egg cells | Hardens after fertilisation

Question 27

How is cytoplasm an adaptation

Answer 27

Contains nutrients ready to supply the growin embryo

Question 28

What do ciliated epithilial cells do

Answer 28

Line tubes

Ciliated epithilial cells in the Fallopian tubes (oviduct) consist of

Answer 29

``` Ribosomes Cytoplasm Cilia Mitochondria Cell membrane Nucleus ```

Question 30

What do cilia do?

Answer 30

Move things along the tube | They contain strands of a substance that can contract and cause a wavy movement

Question 31

Ciliated epithilial cell oviduct moves the egg cell from the ovary towards the

Answer 31

Uterus

Question 32

Because ciliated epithilial cell oviduct is a body cell it has a .......... nucleus

Answer 32

Diploid

Answer 33

``` Similar/ has cell membrane Cytoplasm DNA Ribosomes Different/ no nucleus No nucleus membrane No mitochondria Has plasmid Had cell wall ```

Question 34

How is the shape of a root hair cell adapted to its function

Answer 34

It has a long thin root hair | Increased surface area for absorbing water and diffusion
