Flashcards in Science Biology Deck (25):
1

Magnification

When an image is made bigger than it seems through a special lens

2

Cell wall

A protective layer that surrounds plant cells

3

Specialised cell

A cell that is designed to do one job that other cells cannot do

4

Red blood cell adaptations

A red blood cell has a large surface area which allows more oxygen. Carries oxygen

5

Vacuole

Is found in plant cells it contains all sticky liquid called sap

6

Nerve cell adaptations

Nerve cells carry electrical impulses around your body. They are long and thin and connections at each end where they can join to other nerve cells. This allows them to transmit messages around the body

7

Diffusion

Is the movement of particles from an area of high density to a place of low density

8

Organism

Is a living thing

9

Chloroplast

This is where photosynthesis happens

10

Egg cell adaptations

Jelly layer protects cell and attracts sperm

11

Rate of diffusion

How fast the particles move

12

Nucleus

This controls the cell and contains DNA

13

Microscope

A device used by scientists to observe things that we can not see with the naked eye

14

Sperm cell adaptations

Streamlined head and long tail the tail swims because they have lots of mitochondria which transfers energy.

15

Binary fission

This is how unicellular organisms reproduce and basically clone the cell creating an identical cell

16

Cytoplasm

This is where the chemical reactions in a
cell takes place

17

Specimen

This is something that you are viewing underneath the microscope

18

Root hair cell adaptations

Absorb water and nutrients from the soil

19

Cell membrane

This controls what goes in and out of the cell

20

Slide

The thing you place the specimen on when using a microscope

21

Multicellular

An organism that has more than one cell

22

Mitochondria

This is where respiration happens respiration produces energy

23

Cell

This is what organisms are made up of multicellular organisms are made up of millions of cells, different cells are specialised to do a certain job.

24

MRS GREN

MRS GREN stands for: movement, respiration, sensitivity, growth, reproduction, excretion and nutrition

25

Unicellular organisms

These are organisms made up of 1 cell they are: amoeba, euglena, fungi and bacteria
