Question 1
Cell theory-The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Answer 1
Organelle-1 of the many parts of a cell
Question 2
Cell division-The manner in which cells divide
Answer 2
Mitosis-A process in which cells divide
Meiosis- a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Answer 3
Reproduction-to create offspring
Question 4
Nucleus-the brain or control center of the cell
Answer 4
Plant cell- has a cell wall and chloroplasts
Animal cell-An animal cell is a type of cell that dominates most of the tissue cells in animals. Animal cells are different from plant cells because they don't have cell walls and chloroplasts, which are relevant to plant cells
Answer 5
Osmosis-a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
Question 6
Diffusion-the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms.
Unicellular-Composed of 1 cell
Multicellular-Composed of more than 1 cell
Answer 7
Prokaryote-a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria.
Question 8
Eukaryote-an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
Answer 8
Microscope- a tool used to see things that are very small or microscope
Question 9
Cell wall-a rigid layer of lying outside the membrane of the cells of plants, fungi, and bacteria; it consists mainly of cellulose.
Answer 9
Cell membrane-
  1. the semipermeable membrane surrounding the cytoplasm of a cell.
Permeable- allowing things to enter but wont allow everything to exit.
Answer 10
Cytoplasm- a jelly-like substance found in cells
Concentration
Answer 11
Organism- any living thing
Question 12
Vacuole-a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Answer 12
Blood cellA blood cell, also called a haematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include; Red blood cells (erythrocytes) White blood cells (leukocytes) Platelets (thrombocytes)
Brain cella cell in the tissue of the brain.
Answer 13
Nervous system
Question 14
Spinal cordhe cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system.
Answer 14
NerveAny of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Nerves form a network of pathways for conducting information throughout the body
Question 15
Cerebrummost anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, left and right
Answer 15
Cerebellumthe part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity.
