Presentation transcript:

Warm Up On your Cells page of your IAN, make chart and list the major structures found in each cell. (see example on chalk board) Which cells are prokaryotes and eukaryotes? How do you know? Animal Cell Plant Cell Bacterial Cell

Warm Up Get out your IAN, Agenda, Part of Cell Chart, and something to write with Everything else needs to be on the floor

The cell is the basic structural and functional unit of all known living organisms.

NUCLEUS  Directs all cell activities  Contains instructions for everything the cell does  These instructions are found on DNA  Usually the largest organelle  Found in both plant and animal cells.

CELL MEMBRANE  Allows food, oxygen, & water into the cell  Lets waste products out of the cell  Outer covering, protective layer around ALL cells

CELL WALL  Protects the cell  Gives it shape  Made of cellulose  Found in plants, algae, fungi, & most prokaryotes.

CYTOPLASM  Gel-like substance  Inside the cell membrane  Holds the organelles in place  70-90% water

Quick Check! Match the cell part to the job is does: A. Controls the cell B. Outer protective layer in plants and prokaryotes C. Controls what enters and leaves the cell D. Fills the cell, allowing chemical reactions to occur Number 1-4 in your IAN 1.Cytoplasm 2.Cell Wall 3.Cell Membrane 4.Nucleus

MITOCHONDRIA  Release energy from food  This energy is released by breaking down food into carbon dioxide  Humans have an average of 200 per cell  Found in ALL cells

VACUOLES  Temporary storage spaces  Store food, water, waste  Plant cells usually have larger vacuoles than animal cells

CHLOROPLASTS  Green organelles that make food  Found only in plant cells

CHLOROPHYLL  Found in chloroplasts  A green pigment that gives leaves & stems their color  Captures sunlight energy that is used to produce food called glucose  Glucose is a type of sugar

Quick Check! Match the cell part to the job is does: A. Green pigment that traps light energy in plants B. Storage compartment C. Release energy for cell D. Organelle that holds chlorophyll for food production in plants Number 1-4 in your IAN 1.Mitochondria 2.Chloroplasts 3.Chlorophyll 4.Vacoule
