Life and Living Things

Cells


What are the structures of a cell?

Compare and contrast plant

and animal cells. Name the functions

Of each structure in the cell.


Complete the web with four

characteristics of cells.

All organisms -living things-

are made of

cells.

Cells do the

jobs that keep

organisms

alive.

Cells

Cells are the smallest

part of a living thing.

These cells are like

tiny building blocks.


What is the smallest part of this living thing?

Cells !


BrainPOPCell Structures

  • What are some parts of cells? What do the parts do? How are cells different from one another? How do cells make more cells? What other questions do you have about cells?

Scroll down and click on cell structures.


PARTS of a CELL

  • Cell membrane – the outside of a cell; it controls what comes in and out of a cell.

  • Cytoplasm – The gel-like fluid inside of a cell. The other organelles are embedded in the cytoplasm.

  • Nucleus – The control center of the cell

  • Vacuoles – Act as storage centers – stores water and nutrients and also wastes until the cell can get rid of them.

Parts of Plant Cells

  • Cell wall – additional outer covering around the outside of the cell. It provides extra strength and support to the plant cell.

  • Chloroplast – Where plants make their food. Chloroplasts contain chlorophyll which turns energy from sunlight into food for the plant. Chlorophyll is the reason that plants are green.

What is a microorganism?

Organism – A single form of life; the

simplest level of life in an ecosystem.

Microorganism – very small, often one-celled, living things that are viewed through a microscope


Protists

  • A protist is a single- celled organism that cannot be classified as an animal or a plant. Many protists are capable of producing their own food, like plants. Others eat microscopic organisms, or microorganisms.


How do microorganisms affect us?

  • Microscopic producers make their own food which gives off about half the oxygen in our atmosphere. Microscopic consumers eat other microorganisms. Some act as decomposers and acts as recyclers – eating other dead organisms.
