Thekey differencebetween monocolpate and tricolpate is thatmonocolpate pollens have a single furrow on one side while tricolpate pollens have three meridionally placed furrows. Another major difference between monocolpate and tricolpate is thatmonocolpate pollens are characteristic tomonocotyledonswhile tricolpate pollens are characteristic to双子叶.
Pollen grains are male microgametophytes of seed plants. They producemale gametesor sperms. Colpus is an aperture in the pollen grain of被子植物. It is a long furrow-like aperture. The pollens that have such apertures (colpi) are known as colpate pollens. In angiosperms, there are two types of colpate pollen grains. They are monocolpate pollen grains and tricolpate pollens grains. Monocolpate pollens have only one furrow on one side. Tricolpate pollens have three meridionally placed furrows. In nature, monocot plants bear monocolpate pollens while dicot plants have tricolpate pollens.

What is Monocolpate?
单结肠酸粉是花粉颗粒,一侧有单个沟。这些花粉是单子植物的特征。属于Liliaceae,Arecaceae,Asparagaceae和Ginkgoaceae的植物具有典型的单结肠酸酯花粉。因此,苏铁和银杏主要产生单结肠酸酯花粉。他们的花粉中有持久和可识别的col。通常,单结肠酸粉的最长尺寸为40微米或更小。但是,有多个微米的尺寸的单结肠酸奶花粉。
What is Tricolpate?
Pollen grains that have three furrows are known as tricolpate pollens. Most dicot plants bear tricolpate pollens. However, not all dicots have tricolpate pollens. Due to these colpi, tricolpate pollens possess a shape. Acanthaceae family has characteristic tricolpate pollens. Cerocarpus ledifolius, which belongs to family Rosaceae, and Quercus agrifolia, which belongs to family Fagaceae produce tricolpate pollens.
Eudicots have also been called tricolpates earlier. Having three colpi paralleling the polar axis of pollens is a distinct trait of true dicotyledons.
What are the Similarities Between Monocolpate and Tricolpate?
- Monocolpate amd tricolpate are two types of colpate pollen grains.
- Monocolpate and tricolpate pollen grains are characteristic to angiosperms.
- They have elongated furrows in their pollen grains.
What is the Difference Between Monocolpate and Tricolpate?
单结肠酸盐和三核酸盐是在被子植物中发现的两个基本花粉基团。单结肠酸粉的花粉只有一条长的犁沟,而三氯酸酯花粉有三个长犁沟。因此,这是单滤齿和三层岩之间的关键区别。实际上,在单子叶植物中可以看到典型的单结肠酸酯花粉,而在大多数双子叶植物中都可以看到典型的三氯酸酯花粉。
此外,除了单结肠酸盐,毛莫尔彭酸盐和专门的侵入酸酯外,是单肠结构计学的两种类型的类型,而紫红色,colporate,porate和porate是三氯的类型。
The following infographic summarizes the difference between monocolpate and tricolpate pollen grains.
概括– Monocolpate vs Tricolpate
Colpus is an elongated aperture seen in pollen grains. Some pollens have only one colpus while some pollens have more than one colpus. The pollens that have one furrow are known as monocolpate pollens, and they are found in monocot plants. The pollens that have three furrows are known as tricolpate pollen grains, and they are found in most dicot plants. Thus, this is a summary of the difference between monocolpate and tricolpate.
