Double fertilization is a complex fertilization mechanism of flowering plants. This process involves the joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.
Answer:
The cytoplasm is a jelly like substance that supports and suspends organelles and molecules inside the cell. It also helps move and dissolve materials throughout the cell including waste molecules, proteins, and hormones.
I hope this helps! I tried to keep it short and simple. :)
Answer:
The protein would be incorrect and the protein might not function.
Explanation:
We know that introns carry information but introns not only carry information to build a protein. They have to be removed for the mRNA to encode a protein with the right protein sequence.
If the spliceosome fails to remove an intron, an mRNA with extra "junk" will be created in it. As a result, a wrong protein will be created during translation.
If a wrong protein sequence is created, it will hamper the whole translation process. The protein won't function properly.
B: used up in the process
When photosynthesis occurs the plant takes in sunlight and CO2 and converts it into (C6H12O6) or sugar and O2
Answer:
Channel proteins form hydrophilic channels to passively transport substances down the concentration gradient.
Carrier proteins bind to substances to transport them actively against the concentration gradient. They do not form channels.
Explanation:
Channel proteins are the membrane proteins that serve in transport of small polar molecules and/or ions by making a hydrophilic pore across the membrane. These molecules diffusion through the pore and exhibit facilitated diffusion.
Carrier proteins are the membrane proteins that transport the substances across the membrane by binding to them. They do not form the hydrophilic channels. Carrier proteins serve in the active transport of molecules against the concentration gradient.
