Answer They differentiate into three main tissue types: dermal, vascular, and ground tissue. Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).

CHARACTERISTICS- it's the fundamental packaging tissue that fills the spaces between other tissues and is found most abundantly in plants. they need unspecialised/ undifferentiated cells with thin cell walls product of cellulose. they need large intercellular spaces because the cells are loosely packed.

Plant cells are formed at meristems, and so turn out to be cell types which are grouped into tissues. Plants have only three tissue types: 1) Dermal; 2) Ground; and 3) Vascular. ... plant tissue includes xylem, phloem, parenchyma, and cambium cells. Two views of the structure of the basis and root meristem

In an enzyme immunoassay, the enzyme

antoniya [11.8K]

Answer:

is bound to the constant region of the secondary antibody.

Explanation:

Enzyme immunoassays are the techniques used to detect the presence of antigens with the help of antibodies. Each of the antibody molecules has a constant and variable region.

The primary antibodies are added to the wells. The constant region of the secondary antibody is bound to an enzyme while its variable region is free so that it can bind to the specific antigen.

Addition of substrate to the system is followed by visualization and/or evaluation of antigen as the reaction between enzyme and substrate produce some visible changes such as color change.

As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two

Korolek [52]

Answer:

DNA replication is initiated by the help of these enzymes.

Explanation:

Helicase enzyme helps is unwinding the two complementary strand of DNA by hydrolysing the hydrogen bonds present between the nitrogenous bases of the two opposite strands.

Topoisomerase enzyme help in expansion of the Replication bubble by releasing the super coiling or tension occured while unwinding by helicase. It breaks the phosphate bonds in one of the two strands ahead of replication bubble or fork to release super coiling or overwinding.

Single-strand binding proteins gets bind to the separated strands to stabilize the structure of Replication bubble or to keep the both strand separated from each other.

After photosynthesis, energy that the coral can use is stored in

katen-ka-za [31]

Answer:

Energy is stored in glucose molecules C6H12O6

Explanation:

Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.

These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.

Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).

Eg. for aerobic respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen → carbon dioxide+ water+ energy
