2 Characteristics of Living Things
Lesson 1: Characteristics of Living Things

3 Key Vocabulary

4 1. cell - the basic unit that makes up living things

5 2. life process - A function that a living thing performs to stay alive and reproduce

6 3. organ- a part of an organism that performs a specific function

7 Any living thing that can carry out life processes on its own
4. organism- Any living thing that can carry out life processes on its own

8 5. organ system- A group of organs that work together to carry out life processes

9 6. reproduce- To make more living things of one’s own kind

10 7. tissue- A group of similar cells that work together

11 Notes

12 How are plant and animal cells the same? How are they different?
Plant Cell Animal Cell Mitochondria Vacuoles Cytoplasm Nuclei Cell membrane Chromosomes Cell wall Chloroplasts

13 __________ and __________ _________ have many parts in common, but animal cells do not have _________ _________ or _______________. The _____________ store food, nutrients, and wastes in a cell.

14 Time to test yourself! Can you label this diagram of a plant cell?

15 __________ and some green plants are single celled, ___________ organisms. They give off ____________ as a waste product. They make their ________ ____________. _________ __________ organisms trap ____________ from the sunlight in the _________________ where they make food. _________ organisms do not have a heart or brain.

16 ___________ are __________ organisms with many cells.
___________ are single celled algae that live in water. They are _________ organisms with 1 cell. ___________ are __________ organisms with many cells.

17 Complex organisms have many ____________ kinds of cells
Complex organisms have many ____________ kinds of cells. In complex organisms: ________ make up tissues. Tissues make up ___________. ________ make up organ systems. An example of a complex organism with many cells is a flower.

18 How are simple and complex organisms the same? How are they different?
No distinct organs Some made of single cells Some made of many similar cells Many different kinds of cells Different kinds of tissues Have organ systems Carry out life processes Made of cells

19 Quiz Time! What do all living things have in common? Made of cells
Carry out life processes

20 Life Processes Take in nutrients Grow and develop Reproduce
Release energy Give off wastes React to surroundings

21 In complex organisms… Cells Tissues Organ systems Organs

22 Life Processes of Plants
Lesson 2: Life Processes of Plants

23 Key Vocabulary

24 1. chlorophyll - a green material in plants that traps energy from sunlight and gives leaves their green color

25 2. leaf- the part of a plant that uses sunlight and air to help the plant make food

26 3. photosynthesis- the process plants use to make food

27 4. root- the part of a plant that takes in water (moisture) and nutrients from the ground

28 5. seed- An undeveloped plant sealed in a protective coating

29 6. stem- the part of the plant that carries food, water, and nutrients to and from the roots and leaves

30 Notes

31 In most plants, food is made in the ___________.
A plant has 3 main parts: ________ In most plants, food is made in the ___________. Plants provide us with _________ to breathe. If we had no plants, we wouldn’t have enough oxygen.

32 3 types of leaves: __________ leaves- thick leaves that help the plant store water. (dry areas) _______leaves- help plants trap energy from sunlight. (moist areas) ____________ leaves- grow in dry and cold climates

33 2 types of roots: ____root- one large, main root Examples: _____________ and ______________ _________ roots- roots that branch out in a netlike pattern to gather water from a wide area

34 Match that Root! Fibrous roots taproot

35 Some plants have different stems. 3 types of stems are:
______ stems- covered in a layer of bark and can survive in warm and cold climates Example: _____________ _______ stems- can only survive in warm weather and are held up by water Example: _____________ ______ stems- store water and can survive long periods without rain Example: _____________

36 Match that Stem! Thick stem Soft stem Woody stem

37 Plants use __________ to reproduce. 2 groups of plants are:
_____________ plants- produce seeds in __________ __________. Example: pine trees _ ___________ plants- produce seeds inside _________, and __________ is formed only by flowers. Example: peach trees

38 Most leaf cells have special parts called chloroplasts that contain _______________.
In the chloroplasts during photosynthesis, a plant takes in ______________, ____________ ____________, and ___________. The plant produces __________ and ______________.
