Read the following statements and find out the incorrect statement.
(1) Both stem tendrils and thorns are the modification of axillary buds.
(2) Thorns are woody, curved and pointed structures found in Citrus and Bougainvillea for protecting them from browsing animals.
(3) Opuntia and Euphorbia are found in arid regions. They contain chlorophyll in their stem and carry out photosynthesis.
(4) Stem tendrils are found in gourds and grapevines that are slender and spirally coiled and help plants to climb.
Answer (2)
Statement (1) is incorrect because it falsely states that both stem tendrils and thorns are modifications of axillary buds. Stem tendrils are modifications of the stem, while thorns are modifications of the shoots. The other statements about thorns, Opuntia and Euphorbia, and stem tendrils are correct.
;
To determine the incorrect statement, let's carefully evaluate each one:
Both stem tendrils and thorns are the modification of axillary buds.
Stem tendrils are indeed modifications of shoots, and they typically arise from axillary buds or other parts of the plant structure.
Thorns are actually modified stems in some plants, also originating from axillary buds.
This statement is correct .
Thorns are woody, curved, and pointed structures found in Citrus and Bougainvillea for protecting them from browsing animals.
Thorns in Citrus plants and Bougainvillea act as a defense mechanism to protect against herbivores. However, thorns are generally straight and sharp rather than curved.
This statement is partially correct, but due to the description of 'curved', it leans towards being incorrect .
Opuntia and Euphorbia are found in arid regions. They contain chlorophyll in their stem and carry out photosynthesis.
Opuntia (a type of cactus) and Euphorbia are known to thrive in arid regions, and they use their stems to perform photosynthesis as an adaptation to conserve water.
This statement is correct .
Stem tendrils are found in gourds and grapevines that are slender and spirally coiled and help plants to climb.
Tendrils are indeed present in plants like gourds and grapevines. These structures are slender, spirally coiled, and help in climbing.
This statement is correct .
Therefore, the incorrect statement is statement 2 as it inaccurately describes thorns as 'curved', when they are typically straight.
