Vacuoles:
Sac-like structures. Store food, water,wastes.
Located in the cytoplasm. Plants have a large central vacuole.
Lysosomes:
Membrane bound sacs. Contain digestive enzymes.
Destroy damaged or old cell parts, invading pathogens.
Chloroplasts:
Organelle involved with the manufacture of food in plants.
Located in the cytoplasm.
Contains chlorophyll (green pigment)
Contains enzymes, grana, stroma.
Function during photosynthesis
Centrioles:
Found in animal cells
Function during cell division.
Look like cylinders and are found in pairs near the nucleus
this is stupid the slideshow is down and she's moving too fast-
Cell Wall:
Found only in plant cells.
Made up Cellulose, a non-living material.
Protects and shapes the cell
(she's moving too quickly, why)
Cell Specialization:
Certain cells do certain jobs.
Cells are very specific to what they do.
(ex.- Blood Cells; carry O2 to cells, Nerve Cells: carry impulses, Muscle Cells: moves parts of an organism, Xylem/Phloem Cell: transport materials throughout plants.)
Cell Organization:
Cells are grouped together into units or levels.
These specialized units perform similar functions.
Groups of cells make tissues, groups of tissues make up organs, groups of organs make organ systems, and groups of organ systems make up an organism.
