The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
klio [65]

Explanation:

<u>in the stroma</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.

Animals are associated with
klio [65]

Animals are associated with <u>phyla</u> and plants are associated with <u>divisions</u>

Answer: Option B

<u>Explanation:</u>

There are millions of organisms in the world. They were then subdivided based on the similarity between each groups.  

The Animal kingdom range from complex to simple animals. The kingdom Animalia is further subdivided into Phyla. The phyla is further classified into vertebrates and invertebrates.  

Plants acquire nutrition by photosynthesis. They are autotrophs preparing their own food. Animals can’t prepare their own food hence they directly or indirectly depend on the plants for food. The plant kingdom is subdivided to plant divisions.

Leni [432]

Answer: All the above options are correct about the characteristics of Lumbriculus variegatus.

Explanation:

Lumbriculus variegatus also called the black worm belongs to the phylum Annelida and is used by biologists to illustrate:

-blood vessel pulsations,

-swimming reflex,

-peristaltic crawling behavior,

-giant nerve fiber action potentials.

These studies where carried out on them due to the characteristics they possess. These includes:

-its blood circulates in a closed circulatory system

-Freshwater worm found throughout North America and Europe

-Prefers the shallow habitats found at the edges of ponds, lakes, or marshes

-Feeds on decaying vegetation and microorganisms.
