Science Vocab unit 6 Flashcards
A type of cell that is very simple and does not have a nucleus. The DNA is not inside a special membrane but floats in the cell. Ex: bacteria
Prokaryote
A type of cell that is more complex and has a nucleus, where the DNA is stored.
Ex: plants, animals, fungi, and protists
Eukaryote
are tiny structures that carry out specific functions within a cell.
Organelles
are organelles in cells that produce energy for the cell. They are called the powerhouse of the cell.
Mitochondria
is an organelle within the cells of plants and certain algae that is the site of photosynthesis.
Chloroplast
are the storage areas of cells.
Vacuoles
are like little factories that produce protein
Ribosomes
(ER) is like a highway inside the cell that helps move things around within the cell
Endoplasmic Reticulum
take proteins and other materials, package them up, and send them to different parts of the cell or to other places in the body where they are needed.
Golgi Bodies.
are tiny helpers in the cell that help it divide and make new cells. They help organize the parts that pull the cell apart during cell division.
Cetnrioles
is the strong outer layer of a plant cell that protects it and gives it shape and support. It helps the plant stand tall and keeps the cell safe. Animal cells do not have a cell wall.
Cell Wall
is like a gatekeeper for the cell. It controls what goes in and out, letting certain things in and keeping certain things out. It also helps hold the cell together.
Cell Membrane
is the jelly-like fluid inside a cell that holds all the organelles in place. it helps the cell keep its shape and allows nutrients and other materials to move around.
Cytoplasm
This is how our body keeps everything balanced and just right.
Homeostasis
This is when water moves from one place to another through a special barrier, like a cell wall.
Osmosis
This is when things spread out from where there is a lot to where there is less.
Diffusion
(En-do-sy-TOE-sis) is when a cell large molecules, fluids, or even entire microorganisms by wrapping its membrane around them and bringing them inside.
Endosytosis
(Ex-o-sy-TOE-sis) is when a cell expels things, like water or chemicals, by packing them in a little bubble and sending them out of the cell.
Exocytosis
