CELL Components.pptx: human body anatomy

1. CELL COMPONENTS

2. Cell Membrane
• The cell membrane holds the cell together
and allows nutrients into the cell.
• It’s just like a turtle’s skin - the cell
membrane is on the edge of a cell.

3. Cytoplasm
• Cytoplasm is the watery gel (Jello!) inside
a cell….it’s goop! It holds the ORGANelles.
• Cytoplasm is like the turtles blood and
other liquids.

4. Mitochondria
• Mitochondria is an ORGANelle that releases energy from food.
• Every type of cell has a different amount of mitochondria.
There are more mitochondria in cells that have to perform lots
of work, for example - your leg muscle cells. Other cells need
less energy to do their work and have less mitochondria.
• Mitochondria is like a turtle’s stomach.

5. Nucleus
• The nucleus controls the cell.
• It is the largest organelle in the cell and contains the
cell’s DNA.
• The nucleus is like the turtle’s brain.

6. Nucleolus
• Inside the nucleus is another organelle called the
nucleolus.
• It is responsible for making ribosomes.
• It is similar to all the neuron pathways inside a
turtle’s brain.

7. Chromosomes
• Chromosomes are inside the nucleus and are
made of genes (DNA).
• Genes decide the cells traits and activities (heart
cell, eye cell - such as color).

8. Nuclear Membrane
• The nuclear membrane allows substances
to pass in and out of the nucleus.
• It surrounds the nucleus (the brain) like
the turtle’s skull…protects it.

9. Vacuoles
• Vacuoles are spaces in the
cytoplasm (gel) where food and
chemicals are stored
• It’s like “fat” on a turtle
I am NOT
fat…I’m
just a little
plump!!

10. Endoplasmic Reticulum
• It is a network of membranes throughout the cytoplasm
of the cell.
• It helps to move materials around the cell.
• It is much like the blood vessels throughout a turtle.

11. Golgi apparatus
• It is organelle in the cell that is responsible for sorting and
correctly shipping the proteins produced in the ER.
• The Golgi apparatus are stacks of membrane-covered
sacs.
• They also package proteins to be moved out of the cell.
• It’s like the digestive system of a turtle.

12. Vesicles
• It is a small sac that surrounds material to
be moved into or out of a cell

13. Ribosomes
• Organelles that help in the synthesis of proteins.
• Some ribosomes are found in the cytoplasm, but most are
attached to the endoplasmic reticulum. While attached to
the ER, ribosomes make proteins that the cell needs and
also ones to be exported from the cell for work elsewhere
in the body.

14. Lysosomes
• Lysosomes function as the cell's recycling
compartment.
• Lysosomes contain digestive chemicals that help break
down food molecules, wastes, and worn out cell parts.
• It’s similar to the turtle’s digestive system!
The lysosomes
are stained
RED!

15. Cell Wall
• Cell Walls are only in plant cells
• They make the cell strong and rigid
• They are like a turtle’s shell (but only
plants have them…that’s why grass stands
straight up!)

16. Chloroplasts
• Chloroplasts are only in plant cells
• They contain chlorophyll, which helps
make energy/food from sunlight
• Chlorophyll is green in color.
I’m
green…do I
have
chloroplasts?
