Baobab trunks are adapted to store water in dry climates.
-
Which science is the study of plants?
Botany
Botany covers the structure, growth, reproduction and classification of plants, from mosses to forest trees. Zoology is the equivalent science for animals, geology deals with rocks and the Earth, and ecology studies how living things interact with each other and their surroundings.
-
What type of root is the main edible part of a carrot?
Taproot
A carrot is a swollen taproot that stores food for the plant.
-
Which coffee-fruit structure is the coffee bean?
The seed
The fruit is called a coffee cherry, and most cherries contain two flat seeds pressed face to face. When only one rounded seed forms, it is called a peaberry, and some producers sort and sell these separately.
-
Which tree's bark can be stripped every nine years and simply grows back?
Cork oak
Cork stoppers are made from the thick, spongy bark of the cork oak (Quercus suber). The bark can be harvested repeatedly without killing the tree.
-
Which plant produces soft fibers used to make much clothing?
Cotton
Cotton plants produce soft fibers around their seeds that are spun into textiles.
-
Ferns reproduce and disperse using what instead of seeds?
Spores
Ferns produce spores rather than seeds.
-
Linen is made from fibers of which crop?
Flax
Linen is spun from fibers obtained from flax stems.
-
Which flower part produces pollen?
Anther
The anther is the pollen-producing part of a flower's stamen.
-
What sugary liquid do many flowers produce to attract pollinators?
Nectar
Nectar is a sugar-rich liquid secreted by glands called nectaries, usually set deep inside the flower so a feeding bee, bird or bat has to push past the pollen to reach it.
-
In flowering plants, a fruit usually develops from what structure?
Mature ovary
A fruit usually develops from the mature ovary after fertilization, with the ovary wall often becoming the fruit’s protective outer layer. In some fruits, such as apples, additional flower parts also contribute to the fleshy portion.
-
Which stimulus guides most roots to grow downward?
Gravity
Gravity guides most roots to grow downward, a response called positive gravitropism. Specialized cells in the root cap help sense the direction of gravity.
-
Which nutrient can legumes gain with help from bacteria in root nodules?
Nitrogen
Legumes can gain nitrogen through bacteria living in their root nodules, which convert atmospheric nitrogen into forms the plant can use. In return, the plant supplies the bacteria with energy-rich sugars.
-
What is the edible seed of a corn plant commonly called?
Kernel
A corn kernel is the seed of a maize plant, attached to the cob. The husk is the leafy wrapper, and the silk is the bundle of styles, one thread for every kernel it pollinates.
-
What liquid is boiled down to make Canada's traditional pancake syrup?
Maple sap
Maple syrup is made by boiling down the watery sap tapped from sugar maples in late winter, when freezing nights and mild days drive it up the trunk. The sap is only about two percent sugar, so around forty litres of it are boiled away to make a single litre of syrup.

Lavender and rhubarb die back in winter but regrow from the same roots year after year. What kind of plants are they?
Perennial
The roots stay alive underground through winter dormancy, storing energy that fuels new growth each spring, unlike annuals, which die completely after setting seed in a single season.
-
Which organelles carry out photosynthesis in plant cells?
Chloroplasts
Photosynthesis occurs in chloroplasts, which contain chlorophyll.
-
What structure holds the seeds of a pine tree?
A cone
Pines are conifers, meaning cone-bearers. Their seeds sit exposed on the scales of a woody female cone rather than inside a fruit, and the scales flex open in dry weather to let the winged seeds spin away on the wind.
-
What pigment gives most leaves their green color?
Chlorophyll
Chlorophyll is the pigment that gives most leaves their green color by absorbing mainly red and blue light while reflecting green light. It also captures light energy for photosynthesis.
-
Which structure carries the male reproductive cells of seed plants?
Pollen
Pollen carries male gametophytes in seed plants.
-
Which plant structures greatly increase surface area for water uptake?
Root hairs
Root hairs are tiny extensions of root cells that greatly increase surface area, helping the plant absorb water and dissolved minerals from the soil.
-
What must a dormant seed take in before germination can begin?
Water
A dormant seed is extremely dry. Taking up water swells it, splits the seed coat and restarts the metabolism that drives germination. Botanists call that first soaking-up stage imbibition.
-
What is the tiny plant within a seed called?
Embryo
The embryo is the tiny developing plant inside a seed, containing the beginnings of its root, shoot, and leaves. It remains dormant until the seed gets suitable conditions to germinate.
-
What is the start of growth from a seed called?
Germination
