Disebut daun lengkap apabila mempunyai...
Correct Answer
D. Lamina, Petiolus, Vagina (pelepah)
Explanation
A complete leaf is referred to as "daun lengkap" when it has all three parts: lamina, petiolus, and vagina (pelepah). The lamina is the flat, expanded part of the leaf that is responsible for photosynthesis. The petiolus is the stalk that attaches the lamina to the stem. The vagina or pelepah is the sheath-like structure that surrounds the base of the petiolus where it connects to the stem. Therefore, a leaf is considered complete when it possesses all these three parts.

Explanation
The correct answer is "runcing" because the word "acutus" means sharp or pointed in Latin. Therefore, when it is mentioned that the tip of the leaf is "acutus," it implies that the tip is sharp or pointed, which is synonymous with the word "runcing" in Indonesian.

Correct Answer
D. Mucronatus
Explanation
The correct answer is "mucronatus" because "mucronatus" refers to a leaf tip that is sharp and pointed, often with a small spine or projection. This is in contrast to the other options: "acutus" means pointed, but without the presence of a spine or projection; "obtusus" means blunt or rounded; "rotundatus" means rounded; and "truncatus" means truncated or cut off. Therefore, "mucronatus" is the most appropriate term to describe a leaf tip that is sharp and has a spine or projection.

C. Mempunyai stamen, pistillum, corolla, calix

A flower can be called a complete flower if it has all four main parts: stamen, pistil, corolla, and calyx. The stamen is the male reproductive organ that produces pollen, the pistil is the female reproductive organ that contains the ovary, the corolla is the petals that attract pollinators, and the calyx is the sepals that protect the flower bud. Having all these parts is essential for a flower to be considered complete.

Bunga dapat disebut bunga sempurna apabila...
Correct Answer
D. Mempunyai stamen dan pistilum
Explanation
A flower can be called a perfect flower if it has both stamen and pistil. Stamen is the male reproductive organ of a flower, which produces pollen, while pistil is the female reproductive organ, which contains the ovary, style, and stigma. Having both stamen and pistil allows the flower to produce both male and female gametes, enabling sexual reproduction. This is why a flower with stamen and pistil is considered a perfect flower.

Benang sari berfungsi untuk menghasilkan sel sperma yang akan dibuahi oleh sel telur pada putik bunga. Jadi, benang sari adalah istilah yang tepat untuk menyebut stamen.
