Male cones grow near the<u> lower region</u> of the plant, while female cones are located near the<u> top of the tree.</u>
Sexual Reproduction in Gymnosperms :
The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.

Answer:
The correct answer will be -
1. ATP production- Thylakoid membrane
2. Activated carrier- NADPH.
Explanation:
The photosynthesis reactions take place in the chloroplast which is divided into three membranes: outer, inner and thylakoid membrane. The light-dependent reactions take place in the thylakoid membrane which helps in the production of ATP molecules along with the activated carrier molecule called NADPH.
The ATP molecule is synthesized by the ATP synthase enzyme located in the thylakoid membrane where electron transport chain produces a gradient of protons. These protons help in the production of ATP synthesis explained through the chemi-osmotic model.
Thus, the Thylakoid membrane and the NADPH are the correct answer.
Answer:
During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase.
Answer:
Nucleic Acids are precursor for Proteins.
Explanation:
Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins.
No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy.
No proteins don't carry genetic information.
Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein.
No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.
Please mark it branliest if the answer is little bit satisfying.
Pyruvate is first converted to acetaldehyde by enzyme pyruvate decarboxylase in the presence of Thiamine pyrophosphate and Mg ++. Carbon-dioxide is released during this reaction.
