Photosynthesis is the complex process by which carbon dioxide, water, and certaininorganic salts are converted into carbohydrates by green plants,algae, and certain bacteria, using energy from the sun andchlorophyll.

Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds. This process consists of a series of chemical reactions that require carbon dioxide (CO₂) and water (H₂O) and store chemical energy in the form of sugar. Light energy from light drives the reactions. Oxygen (O₂) is a byproduct of photosynthesis and is released into the atmosphere. Photosynthesis transfers electrons from water to energy-poor CO₂ molecules, forming energy-rich sugar molecules. This electron transfer is an example of an oxidation-reduction process: the water is oxidized (loses electrons) and the CO₂ is reduced (gains electrons). Photosynthesis uses light energy to drive the electrons from water to their more energetic states in the sugar products, thus converting solar energy into chemical energy.

Carolus is a famous scientist created a system that many scientists use to classify organisms today. They use the groups; Kingdom, Phylum, Class, Order, Family, Genus. Later in time, scientists found that there were different kinds of Kingdoms; Animal, Plants, Fungi, Eubacteria, Protists, and Archaebacteria.

The plant kingdom is made up of non vascular plants and vascular plantsVascular Plants- Plants with vessels or ducts that convey fluids.Non-vascular Plants- Plants with no vessels or ducts that convey fluids.Uses suns energy to produce glucose in photosynthesis.

Fungi are mostly many-celled organisms that often grow in moist, dark places. Many give of chemicals that break down the organisms on which they grow. They lack chlorophyll.

A protist is a single-celled organism that has a nucleus. Some can make their own food.

Eubacteria can cause disease, but many are helpful/one kind of Eubacteria takes nitrogen from the air and fixes it so plants can absorb it.Has no nucleus

Can Live in extreme conditionsHas no nucleusI found in hot springsCan live where there is no oxygenSome make natural gas which we use to heat our homes.

All ingest foodThey get their food from somewhere instead of making it themselvesEverything can move on it's own at some point its lifecan reproduce.Invertebrates- Has no back bone- There are mor invertebrates than vertebrates Vertebrates- Has a back bone

Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear.

Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.

The processes that go on in an organism's body.For example- when an animal hibernate, it's body processes slow down.

1. Any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases...

A plastid in the cells of green plants and green algae thatcontains chlorophylls and carotenoid pigments and createsglucose through photosynthesis.
