Plant Cells
Known as "the powerhouse of the cell", these organelles will help to break down food for the plant to use as energy.
What are mitochondria?
This transparent, outer layer of cells protects the leaf against water loss and herbivores.
What is the epidermis / dermal tissue?
The pores formed by guard cells that allow carbon dioxide into the leaf for photosynthesis.
What are stomata?
Although many people think it is a root, this common food is actually an enlarged modified stem.
What is a potato?
This powdery, usually yellow substance is the male reproductive cell created inside the anther.
What is pollen?
Plant cells have one massive one of these to store water, nutrients, and waste, while also maintaining turgor pressure.
What is a vacuole?
hese tightly packed, column-shaped cells located in the upper mesophyll contain the highest concentration of chloroplasts.
What is the palisade mesophyll?
This vascular tissue distributes sugars and other organic products of photosynthesis to the rest of the plant.
What is phloem?
Carrots and dandelions are examples of plants that possess this type of root system, characterized by a dominant central root.
What is a tap root system?
This long, slender tube connects the stigma to the ovary and acts as a pathway for pollen to travel down.
What is the style?
This structural carbohydrate gives plant cell walls their strength and rigidity.
What is cellulose?
In a typical root cross-section, this transport tissue is found in the center, often forming an X- or star-shaped structure.
What is xylem?
Organisms that can make their own food using sunlight.
What are autotrophs?
Carrots, lettuce, potatoes, and celery are examples of this category of plant food because they are edible plant parts that do not develop from the ovary of a flower.
What is a vegetable?
These are the small, egg-like structures found inside the ovary that, once fertilized by pollen, develop into seeds.
What are the ovules?
These tiny channels connect neighboring plant cells and allow substances to pass between them.
What are plasmodesmata?
This tissue is found at the tips of roots and shoots, where it produces new cells for plant growth.
What is (apical) meristem?
Accessory pigments that produce orange and yellow fall colors in leaves.
What are carotenoids?
These specialized structures on the roots of legumes contain nitrogen-fixing bacteria.
What are root nodules?
For successful cross-pollination to produce viable offspring, the pollen donor and recipient plant usually belong to the same biological ______.
What is a species?
This fluid-filled region of the chloroplast surrounds the thylakoids.
What is the stroma?
This plant tissue provides flexible support to young stems and leaves.
What is collenchyma?
This balanced chemical equation represents the process of photosynthesis.
What is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂?
(Accept carbon dioxide, water, glucose and oxygen in word form)
A carrot demonstrates one of these root functions, root hairs demonstrate another, and a large tree remaining upright demonstrates the third.
What are storage, absorption of water and minerals, and anchorage?
Often white or pale in color and strongly scented, these flowers are adapted for pollination by organisms that are active after sunset.
What are nocturnal flowers?
