Nuris is writing a paper on the scientist who first named cells after studying cork under a microscope. Who is her paper about?

Setler79 [48]

Robert Hooke was the first scientist to discover cell. This discovery was made possible by the use of microscope which he invented. With this microscope, Robert examined a cork and noticed pores which filled the entire volume of the thin slices of cork; he called the pores cells. This discovery was made in January 1653.

Why are the cells produced by meiosis considered gametes?

BigorU [14]

Gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).

What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?

dezoksy [38]

Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

And True- Both ATP and NADPH are needed to make sugars.

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.

H+, and oxygen, are formed from a water molecule as it's broken apart.
From photosystem II, electrons are transferred to photosystem I.
ATP is synthesized from ADP along with inorganic phosphate.
To form NADPHH, H+ is added to NADP

If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).
