Inside of a plant Cuticle- waxy layer that keeps the plant from drying out!
Xylem- the tissue that conducts water and nutrients from the roots in vascular plants, and also provides support for the plant
Phloem- the tissue that conducts food
Epidermis- allows light to pass through for photosynthesis
Stoma- let carbon dioxide pass enter the leaf
Palisade mesophyll cell- contains chloroplasts
Spongy mesophyll layer- carbon dioxide moves freely in the space between these cells
Guard cells- regulate exchange of water vapor, oxygen and carbon dioxide through the stoma
Bundle sheath cell- protects the transporting tissue (Xylem & Phloem)
Vein- the whole transport system A.K.A. the Xylem, Phloem, and sheath cell Flower diagram:
Stamen (male reproductive structures): Anther- sack like structure that produces pollen
Filament- thin stalk that holds the anther
Pistil (female reproductive structures): Ovary- in flowering plants produces eggs in ovules
Ovule- a plant egg
Style- long slender part of the pistil
Stigma- the tip of the pistil that is slightly sticky to collect the pollen that fertilizes an egg MITOSIS:
1. Each chromosome is copied
2. The chromosomes thicken and shorten. Each chromosome has two identical copies, called chromatids.
3. The nuclear membrane dissolves. The chromatids line up along the center of the cell.
4. The chromatids pull apart.
5. The nuclear membrane forms around the separated chromatids. The chromosomeds unwind, and the cell divides.
6. the result is two identical copies of the original cell, each with 46 chromosomes.
Meiosis:
1. Each chromosome makes an exact copy of itself, forming two halves called chromatids. They then thicken and shorten and the nuclear membrane dissapears.
2. Each chromosome is now made up of two identical chromatids. Paired homologus chromosomes line up at the equator (center) of the cell.
3. The chromosomes separate from their partners and then move to opposite ends of the cell.
4. The nuclear membrane re-forms and the cell divides. The chromatids are still joined.
5. Each cell contains one member of each homologus chromosome pair. The chromosomes are not copied again during the two cell divisions. (finish later)
VIRUSES: Viruses can be many shapes, crystal, sphere, spacecraft, and cylinders.They can be classified by their shape, the type of disease they cause, their life cycle, or the kind of generic material they contain(RNA or DNA). They are non-living structures that attack cells and multiply by injecting their RNA or DNA, telling the cell to become a factory to make other viruses There are also computer viruses!But these viruses are created by hackers and mess up your computer! (and no they don't actually eat yer fat!) COMPUTER VIRUS: BACTERIA:
Bacteria do not have a well defined nucleus, there are heat loving salt loving and methane loving. MILLIONS OF THESE ARE ON YOUR HANDS RIGHT NOW!!!! USE HAND SANITIZER!!! They use their flagella to move around and they have a cell wall! Viruses are Prokaryotes which means that they don't have a nucleus. the most common type of Prokaryotes are Bacteria! Below is a picture of Archaea Bacteria. They are similar to bacteria in some ways, for example both are single-celled organisms, both of their nucleus are not well defined, they have circular DNA, a cell membrane, and ribosomes, but Archaea ribosomes have a different structure than bacteria. Archaea are usually extremophiles, which means they can live in extreme conditions like high and low temperatures. ARCHAEA bacteria:
Cells make up animals, plants, and US! they are basically the building blocks of life,
everything has cells. there are two types of cells eukaryotic cells, and prokaryotic cells. In the eukaryotic category there are two kinds of cell that there can be, an animal cell and a plant cell. Animal Cell:
Animal Cell ORGANELLES:
mitochondrian: Surounded by two membranes and is the site of cell respiration
Cytoskeleton: Gives support to the cell
Golgi complex: helps make and package materials to be transported out of the cell
nucleus: organelle that contains the cells DNA and is the control center of the cell ribosomes: organelle in which amino acids are hooked together to make protiens
endoplasmic recticulum: makes lipids breaks down substances and packages protiens for the golgi complex
lysosome: digests food particles, wastes, cell parts, and foreign invaders cell membrane: protective barrier that separates the cells contents from its surroundings
PLANT CELL: Plant Cell ORGANELLES:
mitochondrian: Surounded by two membranes and is the site of cell respiration Golgi complex: helps make and package materials to be transported out of the cell
nucleus: organelle that contains the cells DNA and is the control center of the cell
ribosomes: organelle in which amino acids are hooked together to make protiens endoplasmic recticulum: makes lipids brea ks down substances and packages protiens for the golgi complex
lysosome: digests food particles, wastes, cell parts, and foreign invaders cell membrane: protective barrier that separates the cells contents from its surroundings
chloroplast: found in plants and algae, make energy for the plant large central vacuole: stores water and other materials (plant)

I LOVE DOLPHINS BECAUSE THEY ARE BLUE CAN SWIM FASTER THAN 70 MILES PER HOUR AND LIVE IN PODS AND FAMILIES, THEY ARE THE BEST MAMMALS IN THE SEA!!!!!
