In a bird or a bee, the crop is responsible for what?
The crop is a muscular pouch that is part of the bird's digestive system.
Stigma of a plant does what?
The stigma collects pollen at pollination. Stigmas can either be long and
thin or globe-shaped.
Halophile archaebacteria only survive in which type of environment?
Salt loving environment
What is the cilium-like structure present in certain bacteria cells that
allows them to attach to a host tissue?
Fimbria- are appendages found on many Gram-negative (and some Gram-
positive) bacteria that allow them to attach to other bacteria, cells, or
inanimate objects.
,Virus
Viruses can be composed of either DNA or RNA, but not both. If they are
composed of RNA, they are called a retrovirus. Viruses are typically much
smaller than bacteria
Viruses are considered acellular because they do not have organelles or
cytoplasm. All viruses are parasitic, as they depend on a host source to be
able to reproduce
Prophase
Chromosomes are visibly separate, and each duplicated chromosomes has
two noticeable sister chromatids
Propmetaphase
Nuclear Envelope begins to disappear and the chromosomes begin to
attach to the spindle that is forming along the axis of the cell
Metaphase
Aligning along the metaphase plate. "middle"
, Anaphase
Chromosomes start to SEPARATE. "Chromotids" seperate chromosomes
Telophase
Gather on either side of the now separating cell. END of mitosis.
Cytokinesis (Mitosis)
2 diploid daughter cells from mitosis
Meiosis I and II through cytokinesis
