A student encounters a pondweed which, judging from its appearance, seems to be a charophyte. She brings a sample back to her bi
ology lab. Using only a compound light microscope to study the sample, which of the following features should help her to determine whether the sample comes from a charophyte or from some other type of green alga?1. molecular structure of enzymes inside peroxisomes2. structure of sperm cells3. presence of phragmoplasts4. rings of cellulose-synthesizing complexes
Charophytes are the group of some green algae of fresh water. The cahrophyta can be included in both the division and super division. Embryophyta has been emerged from the charophyta.
A student confirm whether the algae is charophyte or not by looking at the specific features. The cahrophytes has well defined sexual characters and the structure of sperm cell, the presence of phragmoplast confirms the charophytes. The cellulose synthesizing ring complex is also present in charophytes.
Thus, the correct answer is option (2), (3) and (4).
point mutation, change within a gene in which one base pair in the DNA sequence is altered. Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations
