1

movement

Action by organism or part of it that changes its position.

2

respiration

Chemical reaction in cells that breaks down glucose to release energy for metabolism

3

sensitivity

The ability to detect & respond to stimuli in internal or external environment.

4

growth

Permanent increase in size & dry mass by an increase in cell number or cell size or both.

5

reproduction

The process of making more of the same kind of the organism.

6

excretion

Removal of waste products of metabolism, toxic materials & substances in excess from the organisms.

7

nutrition

Taking in of materials for energy, growth & development.

8

morphology

the overall form & shape of their bodies.

9

anatomy

the detailed body structure.

10

DNA

study of DNA, to compare the sequence of bases in DNA & of amino acids in proteins of organisms for accurate classification.

11

species

group of organisms that can reproduce & produce a fertile offspring.

12

binomial system

international system that gives scientific name to the organism that is made up of genus and species.
(The first word [genus] has a capital letter, while the
second word [species] has a small letter.)

13

5 kingdoms of living organism

animals, plants, fungi, protoc

14

animals

- Multicellular.
- Cells have nucleus.
- No cell wall or chloroplast.
- Feed on organic substances made by other living
organisms [heterotrophic].

15

plants

- Multicellular
- Cells have nucleus, cell wall & chloroplast
- Autotrophic nutrition [photosynthesis]
- May have roots, stems & leaves.

16

fungi

- Unicellular and multicellular
• Cells have nucleus & cell wall
• Do not have chlorophyll
• Feed by saprophytic or parasitic nutrition
• Some can be eaten, as mushroom
• Some can be used to make food as bread & medicine as antibiotics
• Some can cause food decay or diseases

17

protoctista

- `Unicellular or multicellular
• Cells have nucleus, but may or may not
have cell wall and chloroplast
• Feed by photosynthesis and others feed on
organic materials made by other organisms

18

prokaryotes (bacteria)

• Unicellular
• Have no nucleus or mitochondria
• Have cell walls
• Some bacteria can photosynthesize
• Some are helpful, while some are harmful

19

viruses

They are not considered to be alive, because they don’t have cell membrane, cell wall or nucleus.
• They don’t show the characteristics of living things, they only reproduce inside the host cell.

20

structure of virus

1. protein coat
• 2. genetic material [DNA or RNA or both]
• All viruses are harmful
• Once new viruses are made in the host cell, they will burst out of the cell to invade other cells.

21

fish

vertebrates-
• scaly skin
• gills and fins
• Cold blooded

22

amphibians

vertebrates-
• Have moist skin without scales
• Lay eggs in water
• Larva has gills & lives in water [tadpole]
• Adult has lungs and lives on land
• Cold blooded

23

reptiles

vertebrates-
• Have dry scaly skin
• Lay eggs on land with rubbery shells
• Cold blooded

24

birds

vertebrates-
• Have feathers, beak and wings
• Lay eggs with hard shells
• Endothermic [warm blooded]
• Heart has four chambers
