1
New cards

→Semi permeable

; allows some /specific substances in and out of the cell.

2
New cards

→Chlorophyl absorbs

light energy and converts it into chemical energy by photosynthesis.

3
New cards

turgor pressure

→ Provides to the plant cell and helps maintain its shape.

4
New cards

Flagellum

allows sperm to travel.

5
New cards

fatty sheath

The Axon (extenstion of the cytoplasm away from cell body to carry impulse long distances) is covered with which insulates the cell and speeds up the nerve impulse.

6
New cards

Haploid nucleus

containing genetic material for fertilisation.

7
New cards

Nucleus

: Contains genertic material of the cell in chromosomes which controls cell functions.

8
New cards

bulk transport of water

Do not have a nucleus or cytoplasm to make space for and minerals.

9
New cards

doublr membrane

Mitochondria: Made up of a(n) : inner and outer.

10
New cards

Vesicle

: Sac like structures containing secretory substances eg.

11
New cards

quantity of proteins

→Determines quality and made by the cell.

12
New cards

Ribosome

: The smallest cell of organelles present in the cytopplasm.

13
New cards

Motos

nerve cell: Carries message from central nervous system to the effector.

14
New cards

Vacoule

: Large, permanent, cenraly located in a plant cell but small and temporary in animal cells.

15
New cards

→Cell

: The basic structural unit of life.

16
New cards

Organism

: A group of organ systems which coordinate with each other to create an effective functioning of the body.

17
New cards

egg cell

Acrosome in head contains digestive enzymes to breakdown jelly coat around so sperm can penetrate .

18
New cards

nerve cell

Sensort : Conducts message from sense organ to the central nervous system.

19
New cards

Rough of Endoplasmic Reteculum

: Membranous outgrowth of outer nuclear membranes and has ribosomes attached to its surface.

20
New cards

→ Inner

has many foldings to increase the surface area for enzyme reactions.

21
New cards

Cells

are dead and hollow and connected from end to end to form a long continous tube.

22
New cards

Tissue

: A group of identical cells which work together to perform a specific function.

23
New cards

Organ

: Many tissues which work together to perform a specific function.

24
New cards

image size

The is usually given in centimetres or millimetres so make sure to convert both the actual size and units to be the same to get thr correct magnification.

25
New cards

Cell membrane

that modifies after fertilisation so that only one sperm cell can penetrate.

26
New cards

Cell wall

: Outer most sstructure in the plant cell, made of cellulose and is dead.
