This document discusses several key topics in biology: - Nutrition: All living things obtain nutrients and transform them into energy through photosynthesis (plants) or consuming other organisms (animals and decomposers like fungi and bacteria). - Reproduction: Living things produce new organisms through asexual or sexual reproduction. Asexual reproduction involves one parent while sexual reproduction requires a male and female. - Interaction: Organisms respond and react to stimuli in their environments through senses or other responses. For example, sunflowers respond to light stimuli. - Cell structure: The basic unit of life, the cell, contains organelles like the nucleus, cell membrane, cytoplasm, and vacuoles that allow organisms to carry out functions needed

3.  NUTRITIONNUTRITION::
All living things obtain nutrients form their environment and
transform them into energy.
- Plants produce their own food through photosynthesis.
- Animals feed on other living things.
- Decomposers (fungi/bacteria) feed on the remains of
dead plants and animals.

5.  REPRODUCTIONREPRODUCTION::
Living things produce new organisms similar to
them. Reproduction can be:
- Asexual reproduction occurs when only one
organism is required (bacteria).
- In sexual reproduction two different types of
individuals are required: male and female.

6.  INTERACTION:INTERACTION:
A change (stimulus) in the environment can cause a
reaction (response).
- Animals use their sense organs to detect some
stimuli.
- Some plants have no sense organs but they react to
stimuli too.
 What stimuli do sunflowers respond to?

7.  What is a cell?
A cell is the smallest living unit that makes up a
living thing.

8.  Parts of a cell (animals and plants):
- The nucleus: controls the functions of the cell (such us reproduction).
- The cell membrane: controls what enters and leaves the cell.
- The cytoplasm: substance where chemicals reaction happens.
- The vacuoles: contain water and minerals, which the organism needs
to grow.
vacuoles

9.  Parts of a cell (plants):
- The nucleus
- The cell membrane
- The cytoplasm
- The vacuoles
- Chloroplast: contains chlorophyll needed during photosynthesis.
- A strong cell wall: protects the cell and give it its shape.

10. PLANT KINGDOM
 They are multicellular.
 They make their own food
through PHOTOSYNTHESIS
Plants absorb carbon
dioxide and release oxygen
ANIMAL KINGDOM
 They are multicellular.
 They get energy by
feeding on other living
things.
 Most animals can
move.

11. PROTIST KINGDOM
 They are usually unicellular
(some are multicellular).
 Most protist are in water.
Examples:
 Amoeba: (unicellular
protist). It absorbs food
through a cell membrane.
 Algae: (unicellular or
multicellular). They make
their own food thorugh
photosynthesis.

12. MONERA KINGDOM
 All of them are unicellular.
 They can be on land, in the air,
in water and inside other living
things.
Bacteria:
 We use some of them to make
food (cheese and youghurt).
 Some bacteria feed on dead
plants and animals.
FUNGUS KINGDOM
• They can be unicellular or
multicellular.
• They obtain nutrients from the
remains of dead plants and
animals.
• Yeasts are unicellular fungi.
• Mushrooms are multicellular
fungi.
