Presentation on theme: "Organelles are “Little Organs”"— Presentation transcript:

1 Organelles are “Little Organs”
CELL STRUCTURES Organelles are “Little Organs”

2 cytoplasm A jelly-like liquid that fills up the inside of a cell
Allows materials to be transported within the cell Dissolves substances and allows chemical reactions to take place

3 NUCLEUS Large, dense body within the cell
Regulates the cell’s activities such as reproduction Contains hereditary units called chromosomes

4 vacuole Storage sacs within a cell
Used for storing materials such as water, food, and waste Plant cells have LARGE vacuoles while animal cells have small vacuoles.

5 Cell membrane Barrier that surrounds the outside of an animal cell
The cell membrane in plant cells is surrounded by a cell wall Protects and supports the cell Allows materials to enter and leave the cell

6 nucleolus Small, dense region within the nucleus
Aids in the production of proteins by making ribosomes

7 Cell wall Sturdy, wall-like barrier found in PLANT CELLS, and PROKARYOTES, but not in animal cells. Protects and supports plant cells

8 Endoplasmic reticulum
Series of channels and passageways within the cell May be ROUGH (with ribosomes) or SMOOTH (without ribosomes) Helps in the synthesis of proteins Allows materials to be transported throughout the cell

9 ribosome Tiny structures found within the cytoplasm and along the rough endoplasmic reticulum Sites of protein synthesis within the cells

10 mitochondria Pod-shaped structure found within the cytoplasm of the cell Site of cellular respiration Often called the “powerhouse” of the cell because they release energy

11 chloroplasts Oval-shaped, green organelles found in plant cells, but not in animal cells. The site of photosynthesis in autotrophic cells.

12 Typical animal cell

13 Typical plant cell
