angiosperm

a flowering plant that produces seeds within a fruit

Paramecium

a protist with cilia and two types of nuclei; tiny hairs all over

Nonvascular plants are generally low to the ground because they

cannot transport nutrients

moss archegonia

female; hollow circles

40x

Power objective

4x, 10x, 40x, 100x (oil)

What does the perfect flower have

A flower which has both a male AND female reproductive structure

Gymnosperms

A plant that produces seeds that are exposed rather than seeds enclosed in fruits

Course adjusment

Big knob on microscope

Pines

Cell with wings

will we be using to view prepared slides

Compound light microscope.

components of the compound microscope is used to focus light on the specimen?

Condenser.

bacteria are important in the production of oxygen?

Cyanobacteria.

Archaea

Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan; non-pathogenic

What takes place in the capsule of Marchantia spp.

Meiosis.

Bacilli

Rod shaped bacteria/ pill shaped

Volvox

a green, single-celled aquatic organism that forms minute, free-swimming spherical colonies.

Amoeba

a kind of single-celled organism in kingdom Protista able to move by itself; pseudopod

The most diverse group of plants is the

angiosperms

Eukarya

domain consisting of all organisms that have a nucleus; includes protists, plants, fungi, and animals

Characteristics of Fruit

enlarged ripened ovary, one or more seeds, protects seeds, seed dispersal

objective lens

enlarges the image of the specimen

Plants are a diverse group that can be described as

eukaryotic multicellular autotrophic

The parts of the microscope through which you view the specimen are called

eyepiece/ ocular lense

A structure derived from the ovary of a plant and its accessory tissue is a

fruit

Why does gram stanning help

helps your doctor learn if you have a bacterial infection, and what type of bacteria is causing it to prescribe you the correct medication.

To change the amount of light entering the objective lens, you would adjust the ________.

iris diaphragm

While looking at a specimen under amicroscope, you move the slide to theright. In which direction does theimage move?

left

Moss Antheridia

male has sperm cells

Unlike the seeds of angiosperms, the seeds of gymnosperms

mature on the surface of a cone scale

What is the relationship between trichonympha and termites

mutualistic

Lab Saftey Guidlines

no food or drink closed toed shoes do not touch face no outside things allowed in lab wash hands before beginning lab and after ending tie back long hair wipe down lab tables wear PPE at all times

vegetable is an edible part of a plant derived from ______________

petioles leaves roots flowers

gram negative

pink/red thin to no cell wall

Trichonympha

protist that helps termites digest cellulose

Euglena

protist that moves by a flagellum has a single hair looks like it has a tail

Bacteria

single-celled organisms that lack a nucleus; prokaryotes; pathogenic

Cocci

sphere shaped bacteria looks like tiny balls

spirilli

spiral shaped bacteria

Gram Positive

stains purple cell wall present

Stage

supports the slide being observed

The lignin in vascular plants is responsible for what plant characteristic?

the ability to grow to great heights

The higher you move in objective magnification________

the more the incoming light decreases

fine adjusment knob

tiny knob

Difference between vascular and nonvascular plants

vascular have xylem and phloem to conduct water and nutrients throughout the plant. Nonvascular have no tissues so they exchange water and nutrients through osmosis and diffusion.
