Question

Cataphylls are
A) Floral leaves
B) Special leaves bearing floral buds
C) Dry, papery scale leaves
D) Foliage leaves

Answer 1

Hint: Cataphyll is a reduced, small leaf. Many of them have true leaves that perform photosynthesis and they also have cataphylls that are modified to perform other specialized functions.

Complete Answer:
Cataphylls include bracts, bracteoles, and bud scales as well as many small leaves that resemble scales called scale leaves.
Some cataphylls have a primary function other than photosynthesis. The cataphylls have protective and storage functions.

So, the correct answer is option C, Dry, papery scale leaves.

Additional information:
- The function of cataphyll like bud scales may be short-lived. They are often shed after the need for them is past.
- Examples of various kinds of cataphylls are bud scales, corm scales, rhizome scales, cotyledon.
- The bud scales occur on various kinds of a leaf as well as on flower buds.

Forms of cataphyll:
- Cataphyll performs a transient function, after which they die and shed.
- Those that shed initially are called caduceus for example many Geraniums have caduceus stamens.
- The other forms of cataphyll like spines are persistent but they cannot perform their function until they die whether they are physically shed or not.

Note: Cotyledons are described as a class of cataphyll. Cotyledons of many legumes, conifers even develop chlorophyll and perform the photosynthesis for the germinating part. Cataphyll as a bud scale covers a dormant bud on a deciduous plant. Cataphylls protect buds, especially from desiccation.
