What is the diploid plant that emerges when a zygote germinates?
Sporophyte

What type of plant tissue is undifferentiated cells that can become any type of tissue for the plant?
Meristematic tissue
200
What are the plants that have tissues that circulate nutrients but don't produce seeds?
Seedless vascular plants
200
In which direction are herbaceous stems able to grow?
Both vertically and horizontally
200
What are the tiny bumps on the bottom of fern fronds that house and protect a fern's sporangia?
Sori
200
Where is plants does photosynthesis take place?
Leaves
200
What is the spongy ground tissue in the center of herbaceous stems?
Pith
300
What is the stalk that connects the flower to the rest of the plant?
Pedicels
300
What is the cuticle?
A waxy substance found on the outer surface of plants that protects the leaves, green stems, and fruits of plants
300
What are polar bodies?
Other cells in the ovule that are not egg cells
300
What does xylem do?
It transports water and dissolved minerals from the roots to the rest of the plant
300
What are lenticels?
Tiny pores in the surface of a woody stem that allows air to be exchanged.
400
What is self-pollination?
The ability of plants to produce seeds from the pollen and eggs of the same flower
400
What is the purpose of parenchyma plants?
To contain the substances and cells needed for photosynthesis
400
During angiosperm fertilization, what gets fertilized in the flower?
Both the egg (in the ovule) and the polar bodies
400
What is the purpose of the endosperm?
The fertilized polar bodies that becomes stored food inside a seed to nourish an embryo

Draw the following leaves: trifoliate, bipinnately compound, and simple
Bipinnately compound
Trifoliate 
Simple

What's the difference between a gymnosperm and angiosperm?
Gymnosperm - vascular plants that bear their seeds out in the open or in a cone
Angiosperms - seed-bearing vascular plants that produce flowers and fruits
500
Label the following parts of a flower: ovule, pedicel, anther, filament, stigma, style, petals, and sepals.
Pedicel holds up the flower.

Give the five steps in the moss life cycle.
Leafy shoots originate from germinating spores in the gametophyte stage
Water moves sperm from sperm-producing shoots to egg-containing shoots
Fertilization between egg and sperm to form a zygote in the sporophyte stage
A mature sporophyte develops
The mature sporophyte releases spores
500
What is the purpose of spongy mesophyll vs. palisade mesophyll?
Palisade mesophyll - an orderly row of tightly packed, column-shaped cells in the leaves that contains chloroplasts
Spongy mesophyll - irregularly shaped cells inside the leaf
500
What is the difference between fibrous and taproot systems?
Taproot - consists of one main root and lots of small roots branching off of it
Fibrous root - many small roots that come straight form the stem and not a tap root
