Primary Science Reading Comprehension – (Worksheet 3)
Read the scientific article below and circle the letter of the correct answers to the questions about it.
Understanding Trees
Trees are a major member of the plant kingdom. Trees are a plant type that can be grouped with shrubs and
vines because they all have woody stems. Most trees are perennial which means they live for more than two
growing seasons. Annual plants go to seed (produces seeds) and die after just one growing season. Biennial
plants live for two growing seasons before going to seed and dying. Trees that lose all their leaves in the fall
and grow them back in the spring are called deciduous. In hot dry climates that don’t have autumn or winter,
deciduous trees lose their leaves during the dry season. Trees that do not lose all their leaves in the fall are
called coniferous. Coniferous trees have leaves that look like needles or brushes. Also coniferous trees
produce cones instead of flowers to make seeds for reproduction. Coniferous trees are also called evergreen
trees. Coniferous trees don’t lose all their leaves at once like deciduous trees do. Coniferous trees lose leaves
gradually over time while at the same time being replaced by new leaf growth. This constant leaf replacement
means the coniferous tree is never completely bare like deciduous trees. A tree’s structure consists of its
crown (which includes its leaves and branches), its trunk, and its roots. Trees provide wood (for building and
fuel), habitats for animals and insects, and food (fruit and nuts).
1. How are trees, shrubs, and vines similar?
a. They all produce flowers
b. They all grow from bulbs underground
c. They all can have woody stems
2. How do deciduous trees change in the fall?
a. They produce seeds for reproduction
b. They lose all their leaves
c. They grow back their leaves
3. How long do annual plants live?
a. One growing season
b. Two growing seasons
c. Three growing seasons
4. Cones are produced for reproduction by:
a. Coniferous trees
b. Deciduous trees
c. Biennial trees
5. Evergreen trees get their name because?
a. Their leaves are green needles
b. Their trunks are green
c. They never lose all of their green foliage
