Flashcards in Biology Chapter 1 Deck (26):
1

Magnification

The way of seeing something extremely close up

2

Cell wall

The outside layer of a plant cell

3

Specialised cells

Cells specialised for a particular function

4

Red blood cell adaptation

Suitable for aerobic respiration because they have no nucleus, they are small and flexible and they have a flattened disc shape.

5

Resolution

Resolution is how well you distinguish two objects from each other

6

Vacuole

Store food so cell can grow

7

Nerve cell adaptations

They are extremely long in length and can split

8

Diffusion

It is when particles move to a place with fewer of themselves

9

Organism

An organism is a living thing

10

Chloroplast

Chloroplasts are what conduct photosynthesis

11

Nucleus

Nucleus is what controls a cell, and is where DNA is stored.

12

Microscope

A microscope is an instrument which kets you see close up images of an object

13

Cytoplasm

Is a watery jelly like substance which surrounds the things in the cell and gives the cell its shape

14

Specimen

An individual thing that is used as an example for is species/type.

15

Slide

Is what a specimen goes on under a microscope

16

Cell

A cell is what makes up everything in the world and is what makes everything in your body work

17

Binary fission

Is when something reproduces by dividing in half

18

Rate of diffusion

Is increased when the distance or surface area is increased.

19

MRS GREN

Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition

20

Multicellular

Something with more than one cell

21

Mitochondria

Mitochondria conducts respiration

22

Cell membrane

Is what lets things in and out of a animal cell and is the outer layer

23

Unicellular organisms

Are a organism with one cell

24

Sperm cell adaptations

It has a long tail to swim with and half the amount of chromosomes.

25

Egg cell adaptations

Has half the amount of chromosomes and is very big.

26

Root hair cell adaptations

Are that they collect water in the soil
