Answer:
1) Pollen is released from the anther.
2) Pollen sticks to the stigma.
3) Pollen tube forms and grows through the style.
4) The pollen tube reaches the ovule within the ovary.
5) Sperm fertilizes the egg.
Explanation:
Pollination is a process in which pollen grains are transfer from anther to stigma of the flower. It occurs through wind, water and insect such as bees. When pollen gets mature, it falls from anther to the stigma. There it makes a tube which goes to the ovary. This pollen reaches the ovary through this tube and combines with ovule and fertilization occurs.
Answer:
<em><u>The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.</u></em>
Explanation:
Genes within DNA are expressed through transcription and translation of the genetic code.
The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process
The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.
Answer:
Which of these statements is correct about wood and common salt?
Common salt is a mineral because it has a definite crystal structure but wood is not a mineral because it is organic.
Explanation:
Common salt occur in sea and are made of chemical constituents such as sodium chloride and occur in its natural state while wood is organic as the natural form is the timber that occur naturally in the forest. Before a timber is converted into a wood, it has passed through series of processes before such conversion to a finished product
ok so, lighting, amount of water, type of soil, fertilizer, bugs, pesticides, water contamination, other chemicals. even pets, cats- lol hope that helped!
