Cambridge Biology Exams with all Correct & 100%
Verified Answers |Already Graded A+
Define asexual. ✔Correct Answer-When there is only one parent and all of the offspring are
identical to their parents, because they inherit the exact same genetic information.
Describe asexual reproduction in bacteria ✔Correct Answer-When it reproduces asexually the loop
of DNA in the bacteria is copied so that their is DNA for each new cell.
Describe asexual reproduction in spore production in fungi. ✔Correct Answer-When a spore lands
on a damp surface it splits open and a thread falls out, the tread then spread out through the object.
(usually bread)
Describe asexual reproduction in tuber function in potatoes. ✔Correct Answer--The stem tubers
(underground stems grown from the parent plant) the sucrose is transported in the phloem from the
leaves into the stem tubers where the sucrose is converted into starch.
Define mitosis. ✔Correct Answer-A type of division of the nucleus that gives rise to genetically
identical cells in which the chromosome number is maintained by the exact duplication of
chromosomes.
Define meiosis. ✔Correct Answer-A type of division of the nucleus to reduce the chromosome.
Distinguish between self-pollination and cross-pollination ✔Correct Answer-Self-pollination is
when pollen is transferred from the anther of a stigma of the same flower or the same plant. Cross-
pollination is when pollen is transferred from a stigma of one plant to another of the same species.
Define growth. ✔Correct Answer-A permanent increase in size and dry mass by an increase in cell
number or size, or both
Define development. ✔Correct Answer-An increase in complexity as an embryo grows and gains
new tissues, organs and organ systems
Define pollination. ✔Correct Answer-The transfer of pollen from the anther of a flower to the
stigma
Define chromosome. ✔Correct Answer-A thread -like structure made up of genes. They are found
inside the nucleus and are only visible when a cell is dividing.
Define gene. ✔Correct Answer-A length of DNA, found on a chromosome, that codes for a
particular characteristic.
Define allele. ✔Correct Answer-Any of two or more alternative forms of gene.
Define haploid nucleus. ✔Correct Answer-A nucleus containing a single set of unpaired
chromosomes.
Define diploid nucleus. ✔Correct Answer-A nucleus containing two sets of chromosomes.
