Q

How do you properly focus on a specimen?

A

a. Move the stage down to its lowest position. b. Place the glass slide onto the stage. Be careful pushing it under the clips
that the cover slide doesn’t move or crack.
C. Select the lowest power objective lens. Use the lowest magnification first to
achieve best focus.
d. Turn the coarse focus knob slowly until you can see the cells.
e. Turn the fine focus knob slowly until the cells are in focus and you can see them
clearly.

Q
  1. Some microscopes have a fourth lens called the oil immersion objective (010).
    How is this used and how much is the magnifying power?
A

Oil immersion objective is used for examining details of individual cells (e.g. red
blood cells). Its magnifying power is 1000x.

Q

A person tells you to close one eye when looking through a microscope so that you will properly see the object. Will you follow the person’s advice? Why or
why not?

A

Do not follow the person’s advice. Look through the microscope with both eyes
open to avoid eye strain.

Roots System –

59
Q

branching structure that extend into spaces in the soil and absorb water and mineral nutrients delivering them to rest of the plant.

60
Q

– where some plant store starches (ex. Potato) for them to grow year after year, the energy in starch allow them to grow even though they don’t have leaves for photosynthesis.

61
Q

– secondary plant stem that grows horizontally
-provides stability for the plant esp. it grows supplemental roots (grasses)

62
Q
  • vegetative or structural part – stem (central structure, connects other parts to the roots) and leaves
A

66
Q

The nucleolus and the nuclear envelope are distinct and the chromosomes are in the form of threadlike
chromatin.

A

Interphase

67
Q

The chromosomes appear condensed, and the nuclear envelope in not
apparent.

68
Q

Thick, coiled chromosomes, each with two chromatids, are lined up on the
metaphase plate.

69
Q

The chromatids of each chromosome have separated and are moving toward
the poles.

70
Q

The chromosomes are at the poles, and are becoming more diffuse. The nuclear envelope is reforming. The cytoplasm may be
dividing.
