Cell Walls are composed of cellulose‚ hemicellulose and other material Animal cells do not have cell walls they only have a cell membrane‚ this makes their shape round/fluid they have lysosones which plants do not‚ versus the plant cell which is more angular/rigid. Plant cells have chloroplasts to convert light into energy‚ animals do not. Animal

Prokaryotic cells are single celled organisms that were formed at the formation of the earth‚ so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane

while the matrix is responsible for the catalyzing the oxidation of small organic molecules. Photosynthesis occurs in Eukaryotic plant cells‚ which have the organelle of plastid chloroplasts. The chloroplast is the site of photosynthesis. The thylakoids are formed from the grana and this is where the photosynthetic pigments are round and the location of the light dependent reactions. The stroma is a protein containing cell part that is in the region around the Grana‚ here is where light independent

They lack organelles such as nucleus‚ chloroplasts‚ mitochondria‚ endoplasmic reticulum‚ golgi bodies‚ and lysosomes. Cell wall contains peptidoglycan composed of sugar linked by amino acids. They have a single circular chromosome located in a nucleoid. The main chromosomes consists of circular

in the Plastidal 2- C- Methyl- D- erythritol- 4- phsophate (MEP) Pathway. The production of ABA is accentuated by stresses such as water loss and freezing temperatures. It has a carbon backbone of C15 and is formed after carotenoids‚ pigments produced by the chloroplast which have 40 carbons in MEP during biosynthesis. Zeaxanthin is the first ABA precursor. The transport of ABA can occur in both xylem and phloem tissues. It can also be translocated through paranchyma cells. The movement of abscisic

releasing the used energy into our atmosphere. Four main factors needed to produce these processes are sunlight‚ oxygen‚ carbon dioxide‚ and water. I would explain to Van Helmont that under a microscope plants have cells that have tiny green pigments that contain chloroplast where all of the chemical reactions are computed. In photosynthesis a plant takes in carbon dioxide‚ water‚ and sunlight to produce its food and energy. The sun puts off wavelengths that allow plants to capture photons. To a plant

the leaves from which oxygen and water vapor moves out into the ambient atmosphere and carbon dioxide moves in‚ in a process called transpiration. Once the carbon dioxide moves into the leaf‚ it diffuses into the plant cells and is taken to the chloroplasts by active transport‚ where in photosynthesis‚ it is combined with water to form glucose. Therefore it can be said that plants do not necessarily need a transportation process to move and store glucose and oxygen since these pores account for this

They contain chlorophyll a and c‚ as well as other carotenoid and xanthophyll pigments. When dinoflagellates bloom‚ or overpopulate‚ they tend to change the water to a reddish brown color. Dinoflagellata are sometimes called Pyrrhophyta‚ meaning "fire plants". This is because some species are capable of bioluminescence‚ in which chemicals
