Flashcards in Biology Chapter 1 Deck (27):
1

Organism

Any living thing

2

Nucleus

Controls the cell and is needed to make new cells

3

Cytoplasm

This is the part of the cell where all the chemical reactions take place

4

Cells membrane

A barrier around the cell also it controls what comes in and out of the cell

5

Mitochondria

It is where respiration happens in a cell

6

MRSGREN

An anagram to remember the characteristics of living things

7

Magnification

It is where something gets bigger so you can see in more detail

8

Resolution

It is how much you can see under a microscope

9

Cell wall

Strengthens the cell

10

Vacuole

Its keeps the cell firm

11

Chloroplast

It is where photosynthesis happens in a cell

12

Microscope

An item designed to look at something up close and in more detail

13

Specimen

The specimen is something you observe under a microscope

14

Slide

A glass object that goes under a microscope it holds the specimen on it whilst you look at it through the microscope

15

Cell

Through millions of them cells make up an organism

16

Unicellular organisms

An organism that can survive itself, it is only made of one cell

17

Specialised cells

Cells that are specialised for different functions

18

Nerve Cell adaptation

Nerve cells carry electrical impulses around the body. This makes them able to transmit messages around your body

19

Egg Cell adaptation

The egg cell is covered in a jelly-like substance that attracts sperm cells

20

Sperm Cell adaptation

The sperm cells have a streamlined head and a long tail, the tail swims because it has lots of mitochondria that transfers energy.

21

Diffusion

It is a movement of particles between low and high density places

22

Rate of diffusion

How fast the particles go from a low density place to a high density place

23

Root hair cell adaptation

Root hair cells absorb water and nutrients from the soil. The root hair creates a large surface area for absorbing water and nutrients.

24

Red blood cells adaptation

Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.

25

Binary fission

It is when a cell splits itself in two producing two identical cells
