The microscope then was not designed to see cells that small . It made cells look a bit blurry .Today we have more types of telescopes with high definitions all sorts that even use electro-magnet technology or simple structures . - 7th grader
Nucleus =)
cell walls
Cell walls and chloroplasts
Microscopic structures are structures that can only be observed through the lens of a microscope. Some microscopic structures you might be familiar with are the structure of a cell or the structure of various types of human tissue.
It depends on what the animal or plant is. For humans, the first division results in 23 chromosomes per cell
Cells are mostly as transparent as water. Their structures are difficult to distinguish without using stains to selectively enhance those structures and membranes.
The external structures are observed. The internal structures can be observed using an ophthalmoscope (a lighted instrument) in a darkened room.
The large feathery structures are the gills.
Mitosis
What are the main structures you could have observed if you had removed the exoskeleton of the abdomen? What are the main structures you could have observed if you had removed the exoskeleton of the abdomen? dunno
Study of the factors that influence the observed similarity among structures in different organisms.
A human fetal cell is the cell being observed. The human fetal cell will have a contractile ring before cytoplasmic division begins.
Nucleus, plasma membrane, cilia, flagella
its because ..... yeah !
None have been directly observed. Our ability to analyse in detail the structures of the human anatomy is fairly new. In the short time since we've been able to map neural structures and neurochemical patterns, no significant evolution can be expected to have occurred.
The cast of Observer Observed - 2000 includes: Takahiko Iimura as himself
The cast of Island Observed - 1966 includes: Henry Ramer as Narrator
Yes. During prophase the chromosomes condense to prepare for cell division.
