Non-photosynthetic species of Euglena are sometimes classified as which of the following?
a. zooflagellates
b. sarcodines
c. water molds
d. pyrrophytes
Answer:
a. zooflagellates
Explanation:
Zooflagellates are non-photosynthetic flagellates which lack cell walls or plastids. The mode of their feeding is by phagocytosis or endocytosis.
Non-photosynthetic species of Euglena are consider as Zooflagellates. Zoomastigophora is a phylum within the kingdom Protista. some of the diseases caused by zooflagellates includes African Sleeping Sickness. they have a spherical, elongated body with a single central nucleus and form a symbiotic relationship with other organisms.
Hence, the correct option is a.
During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
