Organelles 1
general term for material inside the cell (contains cytosol and organelles)
What is cytoplasm?
organelles with double membranes that produce ATP required by the cell
What are mitochondria?
Prophase
Metaphase
Anaphase
Telophase
What is mitosis?
A group of cells that work together to perform a specific function?
What is a tissue?
diffusion of water across a selectively permeable membrane
What is osmosis?
internal cell structures that perform specific functions essential to normal cell structure, maintenance, and metabolism
What are organelles?
This is the control center of the cell that contains DNA.
What is the nucleus?
Cells spend most of their lives during this phase where they grow and prepare for cell division.
What is interphase?
This tissue forms glands, cover cavities and surface of the body.
What is epithelial tissue?
compounds passively transported across membrane by carrier proteins
What is facilitated diffusion?
internal protein framework of threadlike filaments and hollow tubules that gives the cytoplasm strength and flexibility and assists with movement of cellular structures and materials
What is the cytoskeleton?
extensions of plasma membrane that move fluids and secretions across the cell surface
What are cilia?
Chromosomes line up in the middle of the cell and centrioles connect to the centromeres of the chromosomes using spindle fibers.
What is metaphase?
This tissue assists in the transmission of impulses from all over the body to our brain.
vesicle inside the cell fuses with cell membrane and discharges its contents outside the cell
What is exocytosis?
cylindrical structures of microtubules that produce spindle fibers to help the cell during division
What are centrioles?
network of intracellular membranes connected to the nuclear envelope that modifies and packages newly synthesized proteins
What is the rough endoplasmic reticulum (RER)?
The last stage of mitosis where the nuclear envelope forms and the two cell membranes begins to pinch away from one another.
What is telophase?
This tissue protects and supports our body and its organs, connects organs together, stores energy, and helps with immunity.
What is connective tissue?
"cell eating" where cytoplasmic extensions surround the object and bring it into the cell
lipid bilayer containing phospholipids that isolates and protects the cell as well as controls entry and exit of materials
What is the plasma membrane?
stacks of flattened membranes that store, alter, and package secretory products and lysosomal enzymes
What is the golgi apparatus?
DNA begins to condense into chromosomes and become visible. The nuclear envelope begins to decompose and spindle fibers begin to appear.
What is prophase?
This tissue generates force and helps with movement of the structures in our body.
What is muscular tissue?
specific molecules in extracellular fluid bind to corresponding receptors on cell membrane and form a vesicle that enters the cell
What is receptor-mediated endocytosis?
