make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf include the upper and lower epidermis‚ the mesophyll‚ the vascular bundle(s) (veins)‚ and the stomates. The upper and lower epidermal cells do not have chloroplasts‚ thus photosynthesis does not occur there. They serve primarily

Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

The cell wall is outer layer maintaining the cells shape while the cell membrane and cytoplasm are located on the inside of the cell wall.

will be larger. Plants can absorb and use light energy because they have a green pigment‚ chlorophyll‚ contained in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as a energy transducers‚ converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy. The equation for photosynthesis can help to predict the

world. They grow in several habitats (in soil‚ in water‚ in the Earth’s crust‚ etc.). The second kind of cell is the eukaryotic cell. These cells contain a nucleus as well as nucleus bond organelles (for example; Golgi apparatus‚ mitochondria‚ chloroplasts‚ etc.). Eukaryotes cells exists in four kingdoms; fungi‚ protists‚ animals and plants. Funguses are decomposers and are vital for cycling nutrients in the environment. Animals and plants differ in cell

of the sun through light and use it to create sugars. Photophosphorylation is the first step of photosynthesis and occurs in the chloroplast. Light is captured by light harvesting complexes. The light excites electrons which excite surronding electrons through resonance induction and excite special pairs of electrons. These electrons help pump protons into the chloroplast lumen creating a proton gradient. Photosystem I also absorbs light and excites electrons which are used to pump more protons. ATPsynthase

The eukaryotic structure consists of the following organelle which includes mitochondria‚ chloroplast‚ the endoplasmic reticulum‚ the Golgi apparatus‚ lysosomes and nucleus. These organelles perform a specific function that help the cell survive. The organelles are separated from the rest of the cellular space by a membrane; it is like having a

Photochemistry‚ a sub-discipline of chemistry‚ is the study of the interactions between atoms‚ small molecules‚ and light (or electromagnetic radiation).[1] The pillars of photochemistry are UV/VIS spectroscopy‚ photochemical reactions in organic chemistry and photosynthesis in biochemistry

cells are as follows: Plant cells contain cell structures like cell wall‚ plastids‚ and large vacuoles. Cell wall provide plant cells rigidity and structural support and cell to cell interaction. Plastids help in storage of plant products. Chloroplasts aid in carrying out the process of photosynthesis to produce food for the plants. Vacuoles are water-filled‚ membrane bound organelles which stores useful materials. Plants have specialized cells in order to perform certain functions for the
